Moin, I just uploaded a file to mphq that shows heavy A/V desync problems with MPlayers mov demuxer. Ie jumpy sound, small loops and desyncs that go up to two secs. The file works fine with -demuxer lavf [Order]_Tengen_Toppa_Gurren_Lagann_-_01_[83DAF271].mp4: --- MPlayers mov demuxer produces A/V desyncs, short loops and choppy sound.
