It's only an issue with the second option -- experimental a/v sync.  With the 
nvidia cards, it's possible to read from a device (/dev/nvidia0) and know 
when the next refresh of the screen is going to be.  Result -- perfectly 
smooth playback.

They'll do something, can't hurt to play around with them.  Try em out, 
different combinations, etc.
