Default 9742/6 xvmc and xv with 8800gtx

Hi all,

I am having a major problem with my 8800 gtx and Xv/XvMC:

(II) NVIDIA(0): Setting mode "1920x1440"
(--) NVIDIA(0): No video decoder detected
(II) Loading extension NV-GLX
(II) NVIDIA(0): NVIDIA 3D Acceleration Architecture Initialized

The first line after the resolution setting is the problem; in addition xdpyinfo shows the Xvideo-MotionCompensation missing with the 8800 (even though it gets initialised ealier in the Xorg.0.log). I do not get this with the same 9746 drivers with a 6800GT plugged in - Xv and XvMC both work fine with the older card.

Could I have bought a "budget" card by mistake without an XvMC support?

Strangely plain old Xv works with xine and mplayer with the 8800, but in mythtv neither "Standard" or "Standard XvMC" work at all (I get sound but a black screen when trying to watch TV or recordings). Everything works with both Xv and XvMC when the 6800GT is plugged in.
