What was the XvMC libs reported by ./configure?
XvMC libs -lXvMCW
Which is the wrapper that loads the library specified by /etc/X11/XvMCConfig
With MythTV 0.20 (or recent svn), this works with the Nvidia FX 5200.
Not sure if this helps, but I recall things *not* working when "XvMC
I am running Nvidia's 8762 release on top of a 2.6.16 kernel.
Also, though I suspect everyone has done this, double check that you
have set the frontend to use XvMC (Television Playback Settings). It is
easy to forget to turn this back on when experimenting.
