You might try just setting it when changing the movie and then turn it off.

MPEG is an inherently computationally-intesive format to decode in software,
and with the overhead of QT's internal event loop you should expect some
inefficiencies with the CPU time left over for all the stuff the Rev engine
has to do.

FWIW, more recent versions of the MC engine have had substantial
improvements with QT playback performance, which should be reflected in Rev
1.5.
