XMV is the audio/video container format used on the Microsoft Xbox console. It is reportedly similar to ASF and typically contains WMV2 video at 640x480 29.97, and CBR audio at 128k.

An open source demuxer exists in FFmpeg/libav: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=blob_plain;f=libavformat/xmv.c

Copyrighted Microsoft source code for a decoder/demuxer is also available: http://sourceforge.net/tracker/index.php?func=detail&aid=1097094&group_id=53761&atid=471491
