Are you running a second X session, or a second X display in
non-mirrored mode w/TwinView?
If I recall correctly, it states in nVidia's driver docs that most
hardware-accelerated functions will work on a secondary X session. See
Appendix R: Configuring Multiple X Screens On One Card.
As far as TwinView and getting XvMC on the secondary display, see
nVidia's driver docs, Appendix I: Configuring TwinView, which states:
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.
I believe XvMC is a hardware video overlay (someone correct me if I'm
wrong), so TwinView mirrored mode, or no hardware acceleration, it
would appear.
