what is your audio headroom set to? set it to 0db will help.

did you encode your movies with nero, or with something else (like x264 or sorenson, etc...) i only tried to play movies encoded with nero digital. but i noticed in full dvd resolution (720x575) that the xbox's cpu power is way to weak... i had to downsample to a width of 592 pixels instead of 720 to be able to play it without any probs...

i tried the examples you gave me, and ... nope, no go on my xbox either... so my guess is that maybe it is indeed h.264 quantisation but maybe the files use some other entropy coding than cabac or cavlc (if that's possible) anyways, nero digital works fine but those do not ... just don't know why

a 720x480 h.264 encoded file at 1517kbps (2-pass encode, no cabal, no deblocking) with ac3 audio (passthrough), 438mb for 42mins file, skips a lot in xbmc. i encoded episode 1 of season 1 of 24, and i see a lot of dropped frames on xbox.
*edit: 720x480 at 1000kbps, 310mb for 42 mins file, also drops a lot of frames.
640x432 at 1000kbps drops less frames (3-4 times less frames dropped). the file is the same size as the previous one, but i guess having a smaller resolution with the same bitrate is easier to decode in h.264...
trying to encode at 624x418 and 900kbps right now.

hello
seems that very recent xbmc builds (03/08/05) are able to play h264 fine. thanks to the use of a cvs version of mplayer (new ffmeg) :d
