When using the new flip4mac with OSX10.4.4 and QT 7.04, jit.qt.movie reads/plays well even with sources like:
Windows Media Audio 9 Professional, Stereo, 48,000 kHz
Windows Media Video 9 Standard, 1280 x 720, 16,7 Mill.
When using asyncread, playback is broken (file is read in but no playback).
Just use jit.qt.movie.help and change read to asyncread to reproduce.
