You don't get the same performance and certain QT features stop  
working when you have alwaysBuffer set to true.  IIRC, The QT API  
function I'm referring to basically tells QT not to draw in a certain  
region.  I *think* you get normal movie playback everywhere except  
for the knocked out region.  I haven't investigated this too much.  I  
just came across while reading a book once.
