Hi Bruce,
I bugzilla'd this problem in 2.2, and it's supposed to have been 
fixed in 2.5 (although since I don't have 2.5 myself yet, I can't 
confirm this).


One workaround was not to use QuickTime to do the transitions, but 
the non-QT transitions aren't so pleasing on the eye. Another 
suggestion was to change the stack's alwaysbuffer property, but that 
didn't fix it in 2.2. Maybe you can try it in 2.5?
