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

MPlayers mov demuxer produces A/V desyncs, short loops and choppy
sound. Using lavf works fine tough

The true CS students do not need to know how to program.
They learn how to abstract the process of programming to
the point of making programmers obsolete.
