And xvideo is never synced with the nvidia drivers when compiz is enabled, even when compiz vsync is on. This is evident from the nvidia release notes which actually state the fact, and from experience as well.
Looks like you're right, this is apparent when taking screenshots of the video. Still, the tearing is hardly visible in most cases -- it's much worse with e.g. Intel hardware and drivers. I wonder why.
