Are you getting the flickering in XV with the current CVS as of this 
afternoon?

If so, can you comment out the src_h and disphoff subtractions, and tell 
me if that fixes it?

No idea why it's need, I think the driver should take care of it. It may 
be just an nvidia driver bug. But XvMC standard is not clear on who 
should do the offsetting, so doing or not doing the offsetting may both 
be proper for the driver writer.
