1. Introduction
Before asking any question or making requests, read this FAQ and any
messages from posters. Most of the regular posters are much more
friendly and helpful than I am so they are usually happy to help out,
but seeing the same questions over and over again is just annoying.
A Mini-faq is posted by Netgear on a regular basis with enough
information to get most newbies started. This big faq has not just
technical info on how to use newsgroup for downloading, but also have
notes on netiquette and hopefully helpful information on various
things that crops up on the ng every now and then.
-----
2. What are alt.binaries.anime and alt.binaries.multimedia.anime?
According to the charter of a.b.m.a.
(ftp.isc.org/pub/usenet/control/alt/alt.binaries.multimedia.anime.Z):
This group is for posting any multimedia file (any format) that is
anime related. The file may be a commercial, trailer, music video,
opening movie, ending movie, special, or entire episode or movie of
anything specifically anime related, including free fansubs which are
widely unavailable to most people (check legal issues in your area, it
is beyond the scope of this proposal to cover the vastness of
fansubs.)
While alt.binaries.anime is a "rogue" newsgroup, the same definition
can be applied to it. "Rogue" newsgroup means that whoever created the
group didn't go through the proper channels in newsgroup creation.
Hence there is no charter or control message for it, so quite a few
newsservers refuse to carry it.
A related newsgroup is alt.binaries.multimedia.repost. It is intended
for reposting of multimedia files from any other multimedia
newsgroups. We often use it for anime reposts to prevent the first two
from getting
too busy.
You can find a lot of information on various anime and their number of
episodes at: [A Janssen]

-----
3. What's with the .rar, .r00, etc files?
Rar files are compressed/split archives. Nearly everything in the
newsgroup are posted in this format. This is done to make successful
download much more likely and it makes reposts much easier. The files
in both a.b.a and a.b.m.a usually run from 50mb+, if these files are
posted in a single post and even one part doesn't make it to
somebody's server, then the file is useless. When the files are split
up, the chances of the individual files arriving intact are greater,
also, even if some of the parts didn't make it, the poster only need
to repost one small part to fill it.
To uncompress these archives, you need to download every single part.
Use a rar program to unrar these files.
Rar program can be found at: http://www.rarsoft.com for all major
platforms, http://macrar.free.fr for macs.
Posting unarchived files, or files archived in a non-RAR format
(especially an uncommon one) is frowned upon and may cause people to
not download your file, not to mention flames in your direction.
There are two kinds of error messages as you unrar a file:
1. Invalid or corrupt authenticity information
In this case, it merely means that the poster used an unregged version
of winrar, so that the error recovery data is not saved. Usually this
is not a problem and the file should extract just fine. Unless if the
files fail the crc check when checking with sfv (see 3b), in which
case recovery method will not work and a repost is required.
2. CRC error
In this case the files are actually damaged. Check the file size
against the other files of the same archive. Sometimes it is possible
to repair the file if the error recovery data is present. Other times,
especially if the file is short by a few bytes, repair will not be
possible.
3a. Rar Recovery Method [Bogus Name]
Yet another good reason to use rar is the recovery record in the RAR
file. In winRAR, highlight the affected R?? file, select the Commands
menu and click Repair Archive. Then rename the resulting archive to
the name of the corrupted archive (after first renaming or moving the
corrupted archive). All should be well.
Another site with good explanations on rar files is at
http://www.freepicgirl.com/nero-x/
3b. What are SFV files?
SFV stands for Simple File Validator and is used to check files if
they became corrupt after transfer. It does this by doing a CRC
(cyclic redundancy check). The poster generates this (text)file with a
SFV-generator and the downloader checks it with a SFV-program to see
if there are any problems. After the check it displays which files
contain CRC-errors and therefore are corrupt.
If a file is corrupt the first thing to do is try to repair it. Since
most archives are created with a recovery record you should first try
to repair the file yourself. See (3. What's with the .rar, .r00, etc
files) on how to do this. If this fails you should make a request for
a repost by using the guidelines in (5. About repost requests (Sod,
some of these parts are incomplete!)). Before you do however first
check the newsgroups to see if it was reposted already or if there are
already outstanding request(s) for it. Don't forget to also check
alt.binaries.multimedia.reposts (ABMR) for reposts.
The programs:
The 2 most used programs for SFV are WinSFV and QuickSFV and are
fairly easy to use. Most SFV's generated can be checked by the other
SFV programs. One exception is WinSFV. The first line for this program
must always include: ';Generated by WIN-SFV32' otherwise it won't work
properly.
The only FAQ for WinSFV that exists at the moment is in Dutch. It is
supposed to be translated to English, but the page hasn't been updated
in a while. It does have a small section in English with the 3 most
asked questions. It also offers the latest version (1.1a) for
download. It is located at http://members.tripod.lycos.nl/winsfvfaq/
The official page for QuickSFV is
http://www.geocities.com/SiliconValley/Mouse/4668/index.html
and always has the latest version for download. A nice feature of
QuickSFV is that it can generate SFV's compatible with WinSFV. That
means it generates the first line that must be included for WinSFV in
a SFV-file.
QuickSFV can be downloaded from:
http://www.geocities.com/SiliconValley/Mouse/4668/
Other SFV generators/checkers are:

4. On uudecode/uuencode, and MIME.
(Help! I'm getting all this garbage text!) [Akito, NetGear]
On an older, less featured newsreader, you may see something like
this:
-------------------------------------------------
>begin 644 filename.r10
>M4F%R(1H'`*6\
M-14`(````$QO9&]SM5_AR06`T8P.$*?D_Z-<^5]TBHM0Y3I[/*P. Checked.
Agent will then check for holes in the message ID list. Obviously
slower, but you won't miss anything. Free Agent doesn't have this
option - instead you have to open a newsgroup with the "download all
headers in selected groups" command.
Another site with good explanations of how to use Agent is at
http://www.freepicgirl.com/nero-x/
NewsGrabber [Severin]
For people with access to more than one news server, NewsGrabber,
[shareware, currently $17 and it's worth it IMHO] from TronTech at
www.news-grabber.com carries the Severin Seal Of Approval. While not
as easy to use as Agent or News Express this thing is AMAZING in that
it can piece together complete posts from parts gathered from any of
the servers you tell it about. ex: a 15 part article, with M1Jax
having 1, 4-6, and 14; M1Naples having 1-3, 11, 13-15; M1Pompano
having 7; AirNews having 1-6, 8-10; and EasyNews having 8-15 is
complete from NewsGrabber's point of view. @home users may find this
particularly useful, since I understand that all of their news servers
are available to all of their customers.
Xnews [Meep Meep]
A excellent newsreader for binaries is Xnews, available at
http://xnews.3dnews.net - It is currently freeware.
It works best as an on-line browser, which is fine for people who have
constant-on connections (cable, dsl, etc).
It can be a little bit cryptic to use at first, but the manual is very
clear. For downloading binaries, parts can be downloaded and held in
an 'archive' while you are waiting for the rest of a post, and
assembled afterwards (this really helps on @home servers, where early
parts of a post usually expire before the last parts of a post).
A newer feature is the 'q-archive' which does not download parts but
can let you queue up article parts across multiple servers and then
download them. Very cool (and space efficient).
Keygens/serials can be found at http://astalavista.box.sk/, use at
your own risk.
Other good newsreader with no one writing a review on them so check
them out yourselves:
Newsbin http://www.newsbin.com
Newsrover http://www.newsrover.com
Linux Newsreaders (darkwire)
PAN (Pimp Ass Newsreader) http://www.superpimp.org/
This is the newsreader I use for all my NG sessions under Linux. It is
very similar to XNews and Agent and seems to have taken the best
features from both. It is currently a work in progress, and requires a
fair amount of memory and resources to run. Since it is beta, it does
segfault occasionally, or gets a hung thread. But otherwise, I use it
as my *only* newsreader, so I rely on it solely for all my news needs.
-----
7. On posting...
New posts are always appreciated. However, both a.b.a. and a.b.m.a.
are very high volume newsgroups. Too many posts can push the older
articles off faster than people can download them. A 100-150mb limit
per day per poster seems to work well. It has been suggested that
300mb is ok as well since it will allow the posting of an entire mpg.
Hopefully this will keep the amount of data manageable. The point
is don't go nuts and post 6-700mb at once and expire earlier articles
prematurely. Newsservers don't have infinite diskspace afterall.
Also, it is highly recommended all posts be rar'd into parts. See
section on rar for explanation. There is no firm rule about how big
each part should be. If the parts are too small, it will make files
management more difficult, as there are more parts to take care of. If
the parts are too large, it will make download and upload (refills)
time much longer. I have seen parts as small as 4mb to as large as
20mb. Personally I lean toward the smaller size since missing parts
take less time to upload and download for the modem users.
There will always be people who want to get their hands on a popular
series. Some of these are requested frequently. It is probably a good
idea for a new poster to ask about what was posted recently to avoid
reposting something that was only posted merely days ago. There are
always newbies who just discovered Usenet and there will always be
people who just missed or catch the end of a posting cycle. However,
if we keep posting and reposting the same thing we'd never get to any
new stuff. For newbies who want something they just missed, the only
thing I can recommend is be patient and wait a few months and see if
anyone is nice enough to repost the entire series.
To say the same thing in short sentences:
- Newbies want lots of stuff, especially popular series.
- Old-timers are tired of the popular stuff and want new things.
- Everyone wants fills and reposts of stuff they missed.
- News servers have a limited amount of disk space.
- Higher traffic causes shorter article retention.
- Shorter retention means we have to download more times per day, or
make more repost requests.
- More repost requests means higher traffic.
Basically we are constantly fighting the disk space limitation. Some
servers are more limited than others, so to keep most people happy we
have to try to limit posting to a level where things won't scroll off
too fast. It's not possible to satisfy everyone at once until all news
servers have infinite disk space.
Lastly, a number of more popular series are available on the web for
downloading, you may find some treasures by a simple quick search on
any search engine.
Here is a guideline on header labels on posts:
[series] ep ## (format/sub or dub) file ## of ##
For large posts that takes several days, a "Day # of #" should be
included as well.
Some newsreaders do not properly thread binary messages unless the
message number part of the subject line is at the end. You should set
your posting software to put the message number after the file number.
I also recommend a readme post of some sort (sometimes file 00/##)
describing the series, how many episodes are there in total, and a
repost request policy if you are so inclined.
Also, if the post is a repost, repack, or parts fills should be
indicated as well. The repack part is especially important. Every now
and then there are folks who help out the original poster of a series
by responding to repost requests so that the poster can move on to
other things. And sometimes this involves repacking the files. Stating
that the reposts are repacks is important so that the downloaders
would know that the repacked parts would not be compatible with the
previous posts. (If you re-rar an episode, more often than not the new
rars can't be mixed with the old ones and still be decodable.)
It is highly recommended that auto-posting software be used for
posting since nearly all postings require multiple parts. Whatever
posting software that you decide to use, it is important to set the
line number per message to below 9000 lines. Anything higher would
very likely to result in the news-server rejecting your post.
Agentpost is a program that is used with the Agent newsreader software
and can be found here:
http://www.skuz.net/madhat/
There is another thing about posting that affects @home users in
particular ever since the 200mb per day per user posting limit was
imposed. Current newsreader and newsposter will uuencode the files and
post it automatically. The process is transparent and is never seen by
the user. The problem is that uuencode process will increase the size
of the file by nearly 37% or so. Since the process is transparent
nowadays the poster don't know how much data they are actually
uploading. So when a poster tries to post a 140mb file, over 200mb of
data was actually uploaded. So @home posters hit the daily upload
limit sooner than they realize.
Power-post [A Janssen]
Another automatic poster for binaries is Power-Post 2000 (PP2K). This
fully automated poster is highly recommended and very popular
because of it's ease of use. You have to set a few simple options like
newsserver, user/password and newsgroups where to post to. The
only thing you'll have to watch is the 'Default Max Lines Per Post'.
As indicated earlier in this section this shouldn't be set higher then
9000, and 7500 seems to be the most used value. Just leave all options
on automated tasks at their default values.
Now all you have to do is add your RAR-parts and SFV to the queue and
select the newsgroup where you want to post to. Make a subject heading
that includes the necessary information and optionally (but
recommended) include some information that would be posted as the
first message in the post known as the '00-file'. See (Subject lines
and 00-file) for information on this. It is important that you include
the filecount, total filecount and the filename with parameters. For
the counters this is $1 and $2 and for the filename it's $F. Do not
make these yourself as there could arise problems with your post. Most
newsreaders combine the different sections of a part together so you
should use the $F and make sure the last character of your archivename
isn't a space. If you would have a 'part .rar' most readers can't
combine it automatically and downloaders must do it themselves
manually and this is time consuming and not necessary. After all
this you can start posting and PP2K will handle completing your post
by reconnecting when necessary, etc. Your first post should be to
alt.binaries.test This is a testgroup where you can see how things
turn out. Just do everything like you should do (rars, sfv) with a
small file and see how it works. If all goes well and looks good, then
you can start posting to the regular newsgroups.
PP2K can be found on http://net-toys.8k.com/
Additional info on subject line and 00-files [A Janssen]
In order for people to understand what a post is you should include a
few
essential things in your header. Of course what it is, the name of the
post,
the episode number, if it is spread over a few days such as 'Day n of
m' and
the format of the post. Most used values for this are:
AVI: A file with the avi extension. This would typically be a
DivX or
MPG4 encoded file.
DIVX: A file with the avi extension and encoded with the DivX
codec.
MPG4(V3): A file with the avi extension and encoded with the MPG4
(version 3) codec.
MPG: A file with the extension mpg.
VCD or DAT: A file with the extension dat. This is a form of a mpg
file.
S-VCD: A file with the extension mpg. This is a special format
and usually
can't be watched with MS mediaplayer. See svcd info in the
file format section
RM: A file with the extension rm which is called a Realmedia
file.
ASF or WMV: A file with asf or wmv extension.
See for information on these fileformats section (10. On file formats
and codecs).
Sub: A file with Japanese audio and English subtitles.
Sami: A separate file for providing subtitles for AVI files. See
the (Subtitles)
section on how to use)
Rt/Smil: Separate files for providing subtitles for Realmedia (RM)
files. See the
section (Subtitles) on how to use.
Raw or Jpn: A file with Japanese audio.
Dub: A file with English audio.
C-sub: A file with Japanese audio and Chinese subtitles.
C-dub: A file with Chinese audio.
Of course some combinations of these are possible like [DIVX, Sami] or
(RM, C-dub, rt/smil). If no language is given for the subtitle-files
it can be assumed they're English.
Values like this are usually in the header with brackets or
parenthesis and separated by commas. Other acronyms you could find are
OP, ED and MV. These stands for opening, ending and musicvideo. The OP
and ED are the opening and ending of a episode or movie. Musicvideo
is usually a self-made musicvideo which features anime. Other things
you could encounter are TV, OVA or OAV. TV is self-explanatory and
means an episode as it aired on Japanese television. OVA and OAV mean
the same thing and stands for Original Video Animation or Original
Animation Video. These episodes were made directly for
Video/Laserdisc/DVD and so were never on television. Usually OVA's
have a bigger budget and feature less episodes and therefore have a
bit better quality. It's possible for OVA's to have a storyline
before, after or in-between the TV-series of the same show.
A few examples of some subjects:
[DAT, Sub] bakabakashii OVA ep 1 - [03/16] - Day 1 of 2 - bakka.r02
//a bit too much? :-)
Sugoi TV episode 13 of 13 (rm, rt/smil) file 33 of 33 sugoi.sfv
harahetta (raw) - file 1 of 30 - hh.r00
Besides a good subject with the necessary info it is also useful to
include more specific information in the first message of your post.
This typically called '00-file' could include other information on the
post like for example: posting schedule, reposting procedures and
schedule, screensize, filesize, archivesize, framerate, summary and
other text about the post, etc.
-----
8. What about hentai/porn?
The charter of a.b.m.a. specifically states:
Things that should not be posted in alt.binaries.multimedia.anime:
- pictures: they belong in alt.binaries.pictures.anime
- sounds/music: they belong in alt.binaries.sounds.anime
- general anime discussion: belongs in the rec.arts.anime* newsgroups
- hentai/erotica material
- non-anime material
That means no hentai stuff on the a.b.m.a. folks!
Now, while a.b.a. is a rogue newsgroup and hence no charter, and
technically no rules on hentai stuff, I (and most regular posters, it
seems) feel rather strongly that hentai should be kept off from it as
well. This is not because of any self-righteous puritanical reason. It
is because of the fact that quite a few ISP's, newsservers will not
carry erotica/porn newsgroups for puritanical reasons. If some self
righteous parents find their kids downloading porn from a non-porn
newsgroup and complain to their ISP, most likely the ISP will simply
stop carry that newsgroup. This will ruin things for other people on
the same ISP who also follow the newsgroup. So please be considerate.
One may argue that since a.b.a. has no charter so there oughtn't be
any restriction on this sort of thing. However, there is a good reason
for treating a.b.a. as a non-hentai newsgroup. In newsgroup naming
convention, newsgroups with sex related material are designated with
"erotica" or "sex", since neither words are in "alt.binaries.anime",
newsservers and isps will treat it as non-sex newsgroup by default. If
the more puritanical service providers discovers the existance of porn
in a.b.a. they will no doubt stop carrying the ng. Just see the
disappearance of misspelled/disguised warez newsgroups from the @home
servers for a potential fate of a.b.a., or ask your servers providers
what usually happens to "stealth" erotica groups.
For people who do want to post this sort of thing, For now I recommend
posting to alt.binaries.erotica.anime, or alt.binaries.hentai. Those
two groups have hardly any traffic, it'd be interesting to see how
they hold up to large multimedia binaries. Posting to
alt.binaries.pictures.erotica.anime is not recommended. The denizens
of that ng seems even more concern about bandwidth than we do.
Recently H anime were being posted to
alt.binaries.pictures.erotic.anime (no "a" in erotic!), check that
one out.
Some users recently started exploring the possibility of creating a
group specifically for anime hentai. Stay tuned on this one.
-----
9. What about subs/dubs?
Anime purist fans (myself included) are not all that thrilled about
dubs and much prefer to watch subtitles with the original Japanese
dialogue. Nevertheless dubs are still anime and most definitely belong
in both newsgroups. I highly recommend posters to indicate clearly
whether their posts are subs or dubs (see posting headers guideline)
so that people like myself would know what not to download.
Non-translated episodes are also posted. These should be identified
with "raw" or "jp", or "csub" for the ones with Chinese subtitles.
-----
10. On file formats and codecs
Popular file formats including .rm, .mpg, and .asf.
.rm RealMedia
RealPlayer can be obtained from http://www.real.com
Again keygen/serials for the Plus version can be found at
http://astalavista.box.sk/
Of all the popular formats, .rm gives the best compression for the
same length of video. There had been people who complained about lack
of quality of this format in comparison with others, however, in the
hands of a capable encoder with a good machine, .rm can be very good.
Also, there are good reasons for using .rm:
1. Not everyone has a high-speed connection, even cable is slow with
the u/l caps on @home. That makes posting large files nearly
impossible. Also people with slow connection will have a better chance
of getting the smaller .rm files.
2. Diskspace-- not everyone has a 20gb drive. I like to collect enough
files of the same series before burning a CD. With incomplete posts,
broken files that are the daily realities of Usenet, having a
gazillion incomplete episodes on my harddrive would take out a lot of
space.
Also, even if every posts are perfect, a considerable of blank cds
will be needed. For instance, the Nadesico series has 26 episodes
(standard length for most anime series), it fits on 2 cdrs when in .rm
format. If it were in something like mpg it'd take maybe 8-9 cdr's.
Now multiply that with the number of series that's been posted in the
past, the number of series that's currently being posted... That's a
lot more cdr's to buy. .Rm is a nice compromise between file size and
quality.
There is an extension for subtitles for .rm format known as RealText:
RealText section [Moomoo]
What is RealText subbing?
RealText is a simple way of subbing rm (RealMedia) format videos.
Instead of adding subtitles directly to the video, RealText subs are
played in a separate panel at the same time as the video.
A posting of anime subbed using RealText would consist of 3 files :
- Video file (.rm extension)
- RealText subtitles file (.rt extension)
- Synchronization file (.smil extension)
How to watch a RealText subbed anime?
To watch a RealText subbed anime, open the .smil file using RealPlayer
instead of the .rm file
How to sub an anime using RealText?
There is a good explanation of RealText and a tutorial here
http://www.lunaarts.com/realtext/index.html
.mpg Mpeg format
Most general format there is, plays on any platform. Best quality
video, period (well, provided the encoder knows what he is doing and
the source video is also high quality). The major drawback is that the
file size is huge.
Can be played by Windows Media Player that's bundled with Win9x.
SVCD format
Also has .mpg extension, but it's in mpg2 format and can't be read by
the more common media player programs. You will need a software dvd
players such as
windvd http://windvdzone.cjb.net
powerdvd
http://www.digital-digest.com/dvd/downloads/pdvd_down.html
sthdvd (don't have a link for this one)
Elecard http://www.elecard.com
About VCD posts (.dat, bin/cue) [Gorunova]
Lately there has been an increase in the popularity of VCD posts.
People post episodes in .DAT or .BIN/.CUE format that some CD burning
software can write directly as a VideoCD.
VCD posts are okay because the picture quality is great, and people
who don't want VCD can convert to other formats using VCDgear and
VirtualDub etc.
However, VCDs are big (650+ megabytes) and so they should be spaced
out over about 4-5 days in order to avoid drowning the newsgroups and
pushing off everyone else's posts. Please have some consideration for
the people on short-retention servers.
.dat files are just mpg converted to vcd formats, any players that
plays mpg1 should be able to play them.
bin/cue is a cd image format, you will need programs such as cdrwin,
fireburner to burn these. Nero also supports bin/cue, but not very
well.
It is possible to extract files out of a bin/cue image file with
isobuster or vcdgear (http://www.vcdgear.net) if neither cdrwin or
fireburner supports your cd burner.
Go to http://cdrsoft.net for all the cd burning programs mentioned in
this section.
Need mpg extension on Quicktime for Macs.
[From Yugo Nada]
Not all files with the .mpg extension can be viewed with Quicktime.
When people pull .dat files off of VCDs they usually just change the
file extension to .mpg, but they're still .dat files.
Quicktime cannot play them directly. Mac users must use a dat2mpg

WMP is fairly buggy on Macs. Sound rarely syncs in full screen mode.
[Addition from xo]
Just for accuracy, QuickTime *can* play (most) .dat files directly
under MacOS, but how well it does so appears to depend on the
hardware. Perhaps the video card or cpu speed: it won't play well on
my older
Mac but the same dats played fine on 2 G3 class machines I tried them
on.
Not all AVI codecs are available for the Mac.
Indeo(R) Video 3
Indeo(R) Video 4
and
Indeo(R) Video 5
are available on the Mac. You are correct in that many of the more
obscure codecs are not available on the Mac

Unfortunately it requires a $10 for the "full-featured" version,
although a free version is available. The free version includes a
time-limited demo of the "full-featured" version (mtv), *AND* includes
a unlimited command line version (mtvp). It can play in regular size,
zoomed, and FULL screen. It even plays the Tylor movie mpeg that many
where unable to play, and VCD (/dev/cdrom, or set by environment
variable). Biggest difference in the 2 versions is the availability
of a GUI interface to the registered version, fine tuning video,
tracking, and fine tuning audio.
Questions about mpgs (TheMan)
Q. I don't like having all these MPEG parts of a movie. I hate having
to watch 10 mins of video then having to open another file! Can I make
a 1 big MPEG?
A. First off, you don't have to join together a huge MPEG in order to
play back a movie continously without human intervention. You can get
a nice software player (haven't looked, haven't bothered), or get a
DVD player software such as PowerDVD or WinDVD to do it. Both of those
softwares support playlist playback. So you can queue up all those
MPEGs and then just play them back. I have found WinDVD's playlist
playback to be better though, with less noticable interruption during
file changes.
Some very smart people out there have figured that they can "join"
together those many MPEGs into one by using the DOS command "copy /b
mpeg1.mpg + mpeg2.mpg bigmpeg.mpg". This goes the same with trying to
use WinZip to zip up all the MPEGs in store mode. What is the problem
with this? It will seriously screw up the MPEG playback hardware or
software because the I/P/B frames are no longer in order. Whats worse
is, if you use WinZip to join them, you will have a PK header at the
begining of the file. Very smart indeed. I KNOW Media Player can play
them back fine, but thats because Media Player is very forgiving. Many
other players and editors out there do not. Try sticking the "MPEG"
into VirtualDub and you can hope it can crash.
If you really want to join together the MPEGs into one, use a utility
to do it properly. One that I know of is MPEGJoin, and that can be
found at http://extra.newsguy.com/~theprof/Readme.html. Please ensure
that when joining the MPEGs that they are the same in spec (bitrate,
interleaving, etc). If you join together a MPEG of different specs,
some weird stuff can happen. This utility will join together the MPEG
by properly interleaving the frames so that it will be compliant to
the IEC/ISO spec (whatever number that is) and thus players and
utilties will be able to handle the resulting file with little or
problem.
Q. How come I can't play the MPEG I copied off of a VCD? other than Windows Media Player won't open it! A. If you
copied the DAT file straight off of a VCD, and renamed it to
.mpg, then that is why you are getting those error messages.
Basically, what happens when you burn an MPEG as a VCD is the
authoring software (EZCD, Nero) inserts/pads some extra info to the
original MPEG on the fly during the burn. The resulting DAT file on
the VCD will have a 10-30% size increase (bloat if you think of it).
But anyway, because of this extra padded info, it can confuse a crappy
MPEG editor or player.
The best practice is to actually "dat2mpg" convert it so that you can
revert the DAT back to an original MPEG form. You should *always* do
this if you have downloaded something off the net (here on aba or
abma, or some site) if the person claims it was from a VCD. Do a
dat2mpg no matter what so that you can check to be sure it is really
an MPEG before you actually do something with that file, such as
burning your own VCD. This util, VCDGear can be found from
http://www.vcdgear.org. VCDGear 2.0, which was recently released has a
GUI interface. While for some of you people who may prefer a command
line interface, can use VCDGear 1.5, which was released not long ago
also.
.asf Active Stream Format
Can be played by Windows Media Player that's bundled with Win9x.
Window Media for Macs will play .asf, as far as I know the player for
Mac is fairly buggy.
A proprietary video format from Microsoft. The quality of a well
encoded asf can rival that of a mpg at considerable smaller size.
However, there are several major drawbacks:
1. It is a Microsoft proprietary format, it will definitely play on a
Windows machine. It will play on a Mac by a buggy player (from what I
learned so far). At the moment I don't know if it will play on a Linux
machine at all. Video in this format cannot be shared by all
downloaders.
2. You need a fairly high end machine to play it well. On my awesome
state of the art Pentium 200 (no MMX) machine, asfs plays like a bad
slide show. Even the highly compressed .rm format plays way better on
it. Remember that not everyone can afford to get the latest PIII
whatever machine.
[From Brad via email] There's a fairly new library called avifile that
plays DivX and .ASF files, among others, on Linux (it uses some
emulation code from Wine to run the Windows codec DLLs). It's at
http://divx.euro.ru/ . Performance seems to vary a lot depending on
the file, but it works with at least some of the files.
There's a movement amoung most encoders to move away from this format
because of its proprietary nature. Also, since there is zero support
from Microsoft on this format, it is very difficult, if not
impossible, to repair an asf file when it is damaged.
Questions about asfs (TheMan)
Q. Why does the sound come first then I see the mouths moving in the
video? (or vice-versa)
A. In this case here, you computer is not fast enough to handle
MPEG4V3 properly. This symptom usually means you have enough dropped
frames to get the video and audio out of sync. You can try these few
things to see if you can get the playback to be in a tolerable rate
(remember you will still get dropped frames).
1) try closing down ALL programs, that includes your RC5DES,
SETI@home, whatever. Make sure you have a bare bones Windows running
except some necessary things such as audio control.
2) In Windows Media Player, while the ASF is opened (good idea to
pause playback), click on File, then click on Properties. Then click
on the Advanced tab. You should see in there the Microsoft MPEG-4
codec in the top box where it says "Filters in use", doubleclick on
it. You should see the CPU (Picture Quality) slider. Move it all the
way to the left. Close down this box, then resume playback and see how
it goes. In most cases you should be able to watch the ASF full
screen. If your system is only a P200 or something, then maybe you are
stuck playing it in a little 1x or 2x size window.
.avi Audio Video Interleave
Can be play by the Media Player bundled with Win9x.
Can be play by Macintosh with QuickTime player. Works just like Media
Player. It's codec based. Now Microsoft could have created a MAC codec
for QuickTime so that MPEG4 and ASF's worked, but you know how
Microsoft is. [NetGear]
A somewhat more obscure format than the previous three. If done right,
the quality of this format can be very good at a small size. There is
a huge drawback for this format though. Several different codecs
exists for avi's. If the encoder use a codec that the user does not
have, the file will not play unless the user finds the codec and
install it. This option is available to Windows users only. It is not
known if Macs and Linux user can play avi's with the more obscure
codecs at all. So while it is a high quality format, users of
platforms other than Windows will not be able to enjoy it.
Most popular codec: MPEG4V1-V3 (default with Windows Media Player)
MPEG4V3(Beta): [darkwire]
AVI mp43 format, also used in ASF

This is MS version of the standard mpeg4, most of the time mplayer2
will try to *find* this code by contacted MS, but will result in a
failure, which is the problem for most people. The version I have
found to work is contained in the package wmtools.exe, beta 4.0
The important file is MPG4c32.DLL version 4.1.00.39.17
MPG4C32.DLL version 4.00.3688 is the last version (as of most recent
revision of this faq) that supported MPEG4V3 AVIs. In other words,
this was in the final beta of Windows Media Tools.
4.00.3845 and up will cough up an error message to you if you try to
play an AVI that's done in MPEG4V3. [TheMan]
New versions on the MS homepage *WILL NOT* work AT ALL, I have tried
this over the weekend (04-22-2000), the version available on MS
homepage is wmtools.exe, release 4.1 Installing a new version, then
uninstalling, and reinstalling old version, will not work, because
windows decides to keep the newer
codec file, you can fix this by running the old wmtools.exe, waiting
till it finishes decompressing the files, then digging through the
'temp' directory for MPG4c32.dll
(NetGear also made an account and put up a copy of it on this site.
http://homepages.go.com/~mpeg4/fxmpeg4.zip)
Just download this zip, it is 4.00.3688. Don't even have to bother
with trying to find an older version of WMTools to "rip" the file out.
You can install the latest version of WMTools, then "patch" it with
that older DLL. Since that DLL is beta, if you have problems with some
weird side effects such as weird color bursts after decompressing the
AVI or ASF, then you know why. The codec has never crashed on me or
gave me any serious problems other than some weird color effects
sometimes when working with the decompressed AVI. [TheMan]
DivX(hacked MPEG4V3) also has .avi extension: [darkwire]
http://divx.ctw.cc
This is a hack of the MS mp43 format, supposedly, the *standard*
versus the bastardized MS version.
Files that are divx or mp43, both have avi/asf extension, essential
what happens is that the FOURCC identifier is changed, from
DIV3(4)<->MP43, but essential the data inside the file is the same.

I have been able to play div3/4 files with a rewritten to mp43 4cc,

Avi/smi files [A Janssen]
It recently became possible for anyone to make subtitles for raw AVI
episodes by using MS SAMI. The extension for these files is smi. They
must have the same name as the video and be in the same directory.
They then can easily be viewed with MS mediaplayer. How you can watch
the video+sub together:
In Microsoft Media Player 6.4 : In menu 'View' check the item
'Captions'
Microsoft Media Player 7 : In menu 'View' go to the sub-menu 'Now
Playing Tools' and check 'Captions'
One disadvantage of mediaplayer is that you can't watch the video with
the captions in full screen. There are currently two programs that can
display them in full screen. They are the (Korean) program AviText and
DVlaD. AviText takes the subtitles and places them inside the video
while DVlaD uses mediaplayer (must be installed) and displays them at
the bottom. The quality of the text in the subtitles are a little
smoother in DVLad.
If you want to make SAMI's yourself you can use a texteditor or one of
these programs which make it a little easier by including more
automation in timecodes, etc.: SubSync or Magpie. Make an announcement
that you're working on a translation of episode n for series xx, so
that nobody else is doing the same thing. This can prevent a lot of
aggravation and time-loss.
All these programs (and more useful info) can by found on Zen's
website at: http://www.geocities.com/zenwebpage/

11. Help! My news-server bites! What can I do?
Short answer: Get a new news-server.
Long answer:
Get a new news-server. If your news-server hardly ever get any
complete parts, no amount of repost will help.
The best solution is to spend money to subscribe to a premium
news-server. See alt.binaries.news-server-comparison for more
extensive information.
For those who are financially challenged, there are free, open
news-servers out there. This is not a good solution. A.b.a and a.b.m.a
are both very high volume newsgroups. Open news-servers usually cannot
handle the large volume for long. Chances are if you find an open
news-server it will either go down, or be closed not long afterwards.
For more information on where to find open news-servers, see
alt.free.newsservers.
If you don't get either of the newsgroups mentioned, go to
www.deja.com.
Special section for @home peeps:
The following 3 servers are particularly reliable in terms of new
posts and completeness.
news.rdc1.on.home.com
news.rdc1.sfba.home.com
news.rdc1.sdca.home.com
The following 2 servers have much longer retention time (5-6 days)
than others:
news.rdc1.tx.home.com
news.kenner1.la.home.com
@home users are lucky in that they (unofficially) get access to ALL
@home news servers. Access to servers other than your default one is
throttled - you can only open about 5 connections to each one, and the
data rate on each one is limited - but it's still a very useful way to
look for missing parts. There is a list of @home servers that
occasionally gets posted. Ask for it if you can't find it with a web
search.
If you are willing to make the effort to check three or four
high-retention servers, you will probably end up making about 4 or 5
times fewer fill/repost requests. It's polite to make a reasonable
effort to find the files yourself before imposing on someone to repost
them for you.

13. Misc.
Batch file for deleting trailing underscore: [Inc]
Here's what the bat I have used for quite awhile. Note, it is
pointing to the directory where Agent puts the anime parts I dl -
change to suit yourself:
DEL_UNDL.BAT
c:
cd \media\anime
ren *.???_ *.???
If you want to go to different directories it would be easy enough to
change the path to a parameter ( %1 ) that you could pass within the
Shortcut, one for each directory you use.
The only bug is if you try to rename to an already existing name, the
bat aborts entirely.
Also, the whole thing can be one statement if you prefer (and with the
variable):
ren c:\media\anime\*.???_ *.???
or
ren %1\*.???_ *.???
called like:
DEL_UNDL. c:\media\anime

Files rename under *nix [Astrogeek]
Most MS Windows users take for granted the GUI's ability to easily
deal with
any kind of file name. Basically, what you see on the screen doesn't
really
matter as long as you know what it is... click-click, done. However,
when
posting to any forum in which interaction with other operating systems
is a
possibility, the use of more standard filenames should be considered.
For
example:
[Anime Group] Kewl Anime.rar
Looks just like that on a UN*X directory listing, for example. But it
must be
referred to as follows from the shell:
user@puter:/animeDL$ \[Anime\ Group\]\ Kewl\ Anime.rar
Not pretty, and definitely not easy to type quickly in a shell without
TAB
completion. In addition, when attempting to uncompress these files,
the
following error results:
user@puter:/animeDL$ unrar e \[Anime\ Group\]\ Kewl\ Anime.rar
UNRAR 2.50 freeware Copyright (c) 1993-99 Eugene Roshal
No files to extract
user@puter:/animeDL$ _
In my experience, filenames with brackets, braces, non-English
characters, and
funky stuff in general do not work with the command line unrar
utility. Since
RAR is the compression format used in alt.binaries.*.anime, and the
command
line unrar utility is the only native method for unarchiving these
files under
Linux/UN*X AFAIK...you get the idea. These files must be renamed to
be used.
To summarize:
[K-Rad Gruppe] Killer Anime.rar = YUCK
K-Rad Gruppe Killer Anime.rar = *COUGH* (but it works)
KRG_KillerAnime.rar = better
krg_killeranime.rar = even better (if you're super nice :-))
krgkanim.rar = 8.3 format, the best compatability. Any OS that
_requires_ this
format probably cannot view your files anyway...this may be redundant.
Filenames _within_ the RAR files are another issue. I have not yet
run into
problems with any software besides unrar. However, if you want to be
nice, it
probably wouldn't kill anybody if you used a clean filename.
Windows and Linux/UN*X users CAN get along if we just try a little bit
:-)
(PLUG) Please use DivX ;-) and not patented MS codecs! (END_PLUG)
-----
A more verbose explanation of uuencode:
Here's what this means "begin 644 filename.r10". Save this uuencoded
text as filename.r10 with permissions 644 (that number is a Unix code
that means let everyone read the file, and let the owner modify it).
You may also occasionally see messages encoded using some other system
such as Base64. The principle is the same. Usenet was designed to
transmit messages containing only printable letter, digits and
symbols. Binary files like anime episodes containa wider range of
data, so that data has to be transformed into text before posting it
to Usenet.
Uuencode, also aka uuencode/uudecode, is one of the popular forms of
binary file distribution along the realms of passive file
distribution. (Meaning it's not done in real-time, files are sent but
received later, not instantly). Email and newsgroup messages are of
such type.
Originated from UNIX systems, (thus the UU means Unix-to-Unix) it is
used by users who wish to send binary data to others who are using
software that's not capable of processing binary code. Something like
this would be a unix-based email client like PINE.
Basically how uuencode works is that it takes whatever binary
attachment you are sending, it may be a WinRAR archive, an .rm or some
executable; and translates (encode) that file into a HUGE string of
text garbage that only someone with the decoder can convert back to
the original form. This way, it simplifies the transmission as no
special protocol and/or software is needed. (Nearly all computers can
do text transfer without problems. I say nearly because there is
always some exceptions to the rule in the world of computers - just
look at Windows)
In summary, uuencode is simply a utility if you wish, that translates
binary code into encrypted text to be sent: 1) Over a medium that
cannot process binary transfers. 2) To a individual using software not
capable of receiving binary attachments.
Now for MIME... (this is the uglier one as it involves Windows and Mac
OS...)
Raw codes of MIME looks something like this:
-------------------------------------------------
If your mail reader is text-only
>This is a multi-part message in MIME format.
>
>------=_NextPart_000_004B_01BF8C4A.98F7ABE0
>Content-Type: text/plain;
> charset="big5"
>Content-Transfer-Encoding: 7bit
-OR- if your mail can read MIME encoded mails but can't handle the
file type
>MIME-Version: 1.0
>Content-Type: multipart/mixed;
> boundary="----=_NextPart_000_000C_01BF8499.08997280"
>X-Priority: 3
>X-MSMail-Priority: Normal
>X-Mailer: Microsoft Outlook Express 4.72.3110.5
>X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3110.3
-------------------------------------------------
Again, current newsreaders will decode MIME automatically like
uuencoded files.
MIME, aka Multi-purpose Internet Mail Extension, is an extension of
the original E-mail protocol (an agreement between computers that data
of such type [email] will be transferred using this set of specifics)
to exchange different types of data. (Such as webpages, audio, video,
and of course, text files)
How it works is that servers sending the transmission will insert MIME
headers into the body where it instructs the client on HOW to handle
the binary data that's to follow. Say it may be a webpage, then the
client knows to launch the web browser to handle the attachment. (Or
RealPlayer for those anime .rms ^_^ )
Currently only so many MIME types are registered on the Internet
Assigned Number Authority (more info? you're on your own), as new file
formats are surfacing as the days go by, the Internet MIME databases
will be updated accordingly and YOU as the user, will need to download
the appropriate software and update your computer so they can handle
such files. Fortunately most installation programs take care of this
for you on most platforms. (Called file associations - ie: files with
.RM extension will be handle by RealPlayer, .HTM - web browser, MP3 -
Winamp...etc)
In summary, MIME is a string of instructions inserted at the beginning
of any web transmission that instructs the client receiving this how
to deal with the binary attachments that's to come. By equipping
themselves with the associated software, (which is usually widely
available on the Internet) users will not have to hunt down software
every time they receive a binary attachment.
Now, I've stripped down the definitions to avoid the complicated
techno jargon, there is MUCHO to know about MIME but that I think is
beyond the scope of this FAQ. There are numerous documents out there
floating on the web on MIME and can be easily found using a search
engine like www.google.com
The main difference between MIME and uuencode is that MIME is more
user-friendly to newbies as it takes the guesswork out of the user on
what software is used to deal with this piece of binary code. But
uuencode is computer-friendly as it does not require fancy software to
be able to receive such type of information.
Uuencode is the most preferred transmission type because most
newsgroup servers will not handle binary transmissions therefore MIME
is not recommended here at a.b.m.a. Make sure you are using a reader
that is capable of uuencode or else you might have some complaints (or
nasty comments from our "respected" SWong) coming your way =) |
