If you were using the PVR-350 for TV-out, make sure there is nothing
in your xorg.conf file that might be conflicting with the new NVidia
card. I guess there could be some remnants that might cause a conflict
somehow - did you dump your existing xorg.conf file and create a new
one for the 6200?

Are you still loading ivtv-fb?
