I'm also having problems with the audio syncing up with the video when playing dvd's. I only run dvd's (and originals, not copies) so I couldn't comment on other files. When I play the same dvd's in MPlayer CE 0.75 there are no problems with the audio. I reinstalled IOS 202 to base 57 using Herme's 5.1 and the problem persists. I'm running 4.1u. Is there something else I can try?
