Can Xbox play H264 using XBMC (Xbox Media Center)? What about Xbox 360?
Yes it can. However some files play pretty slow, not sure why it happens (my H264 encodes work fine, 2-3 other files I tried play very slow). I’ll have to do some tests to confirm what caused that. Remember that Xbox doesn’t have the fastest CPU out there (Pentium 3 733MHz) so to be honest the nice playback of most H264 files impressed me. About the new Xbox 360, the media player it contains plays pretty much nothing besides WMV files, so until something like XBMC comes out for 360 you can only display H264 by a streaming solution using a PC.
