That's all I'm worried about, really..  I believe there's some assumptions 
that the audio output will be writing in video frame length chunks in the a/v 
sync code, but, unless a soundcard refuses to set the fragment size to 
somewhere near the requested amount, I don't _think_ it'll be a problem.

Eh, good enough for me, then.  Can always revert it or add code to disable 
it..  Bruce, would you mind applying it? =)
