[PD] playback noise with video

I am getting noise and disruption to audio stream when I am using gem's 
pix_movie object. The noise happens only when I 'run' the movie. most of 
the time its in 'freeze frame' mode with some movement of the graphic 
objects (translation, rotation) and that works fine with the audio. But 
when Gem needs to play the movie I get audio problems.

I am running it on a brand new G5 mac with 4gb RAM, and dual processor, 
which I thought should be enough processing power to run smoothly.

Any ideas about ways of reducing this problem? I am trying to use 
dufferent encoders for the quicktime movie and, I think, some are worse 
than others, but I don't know enough about the differences to make any 
inform decisions. Anyone knows more about how Gem handles movies?
Is it possible to set the system priorities on OSX to give audio higher 
Any other ideas?
