And of course the API includes DelayNodes....  Those could really mess 
up AV synchronization.  You could try to add equivalent delay on a 
separate video path, but likely they wouldn't match perfectly.  Perhaps 
well enough, but...  Also, it might be painful to re-combine them, and 
"correct" synchronization may be lost at that point (you might be stuck 
with however close you had it at the recombination point).
