[visionegg] Audio in Quicktime movies

I am experiencing another bug with the playing of quicktime movies,
and I'm wondering if anyone has advice.
I am able to play quicktime movies in my VE script.
But, the audio is distorted as follows: it seems that the
audio is playing at twice the rate of the video, and the
sound distorts as it plays quickly.
- Playing wav audio is no problem, and happends throughout the script.
- When I load the same quicktime movie using the puicktime.py demo
 it works.  In my script, I pre-load about 15 movies, store them in a list,

 and play them one at a time (as positive feedback).  The code used
 to play the movie is copied directly from the quicktime demo.
- Is it a memory issue?

Thanks
Ted
