I will try to check this on my system.

But here another hint, maybe more interesting for Apple though: The bug 
does -not- occur if another process uses a lot of CPU time. We encoded 
a quicktime movie into mpeg2 and while this was using about 90% and 
while encoding the vcd i wanted to show the bug to a friend and it did 
not work.

But besides this, is there any chance that we can optimize our initial 
performance problem ;-)
