[jitter] Re: metro sometimes unstable not accurate movie playback

I should also point you to my optimization patches I posted earlier in  
the list. They can be useful to expose some small performance gains  
that can help ease out any inherit stuttering.

If you patch is single channel and well suited, Josh and Lukes  
workaround that ive expounded on in the last two patches can make a  
pretty big difference in performance/stutter.
