The only thing I could find in the readme was:
Q: Do video overlays work across both display devices?
A: Hardware video overlays only work on the first display device.
The current solution is that blitted video is used instead on TwinView.
Does that mean 2 cards or 2 outputs on the same card? Dunno.
Heres is my XF86 config

RE: [mythtv-users] XvMC
David,
Post your XF86Config-4 file and I will take a look if I can get some time.
Did you get a chance to look at the Nvidia README? I haven't looked
at it since you first posted, but my feeling is that this should be
possible.
