Okay, so most of my problems were lack of understanding of the nvidia  
options that could go in xorg.conf. I still think that it could  
probably be configured better, but I got it playing video without any  
jerkiness or sync issues. If anybody's interested I'll post my xorg,  
and the settings I've got working.
