List of file formats working on Apple TV
This is just a list of various file formats tested playing natively on the Apple TV (i.e. through Frontrow). The codec sources are noted, if needed. Drop the .component bundle in /Library/QuickTime on the Apple TV.

If you can add to these tables, please do!
|DivX||.avi, .divx||Yes||Perian, OS X Codec Pack||Free|
|720p DivX||.avi||??||Perian, OS X Codec Pack||For one user, video stutters every 10-15 seconds, audio never skips. Can I get confirmation either way on this? please link to a file as mine plays everything except 1080p|
|Flash Video||.flv||Yes||Perian||Free, video file must load completely before playback|
|H.264||.mp4, .m4v||Yes||Included||Supports Main Profile with some exceptions: "QuickTime WILL NOT support 8x8 dct and intra prediction, b-pyramids, lossless encoding, etc. As well as anything from the High Profile."|
|MPEG-2||.mpg, .mp2, .vob, .m2v||Yes||QuickTime MPEG-2 Playback||$19.99, does not play transport streams, reports of choppy video|
|XviD||.avi||Yes||Perian, OS X Codec Pack||Free|

Request: Could someone please post a link to a compiled copy of the SVN of Perian. I tried grabbing the source, and compiling it but am getting a bunch of errors (this is on a PowerPC OS X 10.4.9 box)
NOTE This build is not supported by the Perian project in any way. If it causes your apple tv to explode, they will not replace your apple tv.
Perian built from trunk has been uploaded here. It has been tested on an Intel MacMini but not on an AppleTV. Two tiny hacks had to be done to compile, but I was able to watch two MKV files with no trouble.
NOTE Perian from trunk (as of 2007-04-20) does not work entirely on the AppleTV. It plays audio and subtitles (if available), but no video on any of a dozen test cases. Very likely that /something else/ needs to be added / modified before Perian will work with Matroska files on the AppleTV.
UPDATE VLC can play Matroska files on the AppleTV, *but* it is evident that the hardware cannot handle high bitrate files. It plays 480p decently (some skips), but 720p is unwatchable and 1080p will never get past the first frame. The VLC console will simply spit out a bunch of warnings:
 ffmpeg decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)
