What movie formats can I play on Xbox 360?

What formats can my Xbox 360 play? When I try to play a movie off my USB on the xbox, often it works and sometimes it just comes up with a error saying that Xbox can't read this format.

According to Microsoft's support page, you can use the following codecs when streaming from USB: WMV(Unprotected), Mpeg4, H.264, AVI.

Further investigation of that same page reveals that that means you can use the following file formats: avi, .divx, .mp4, .m4v, mp4v, .mov, .wmv

Also, when playing something from USB, the file can be no larger than 4 GB. It also cannot play DivX files older than DivX 5.0.

A general rule of thumb is that it will almost ALWAYS play a wmv file, but I've had some luck with avi files that have MP3 audio, some mp4 files and even more files listed after the jump to Support
