There is a known but poorly understood performance issue with 2.6
kernels, PCI video cards, and the NVidia proprietary drivers.  The
symptoms are exactly as you describe.  It appears to be independent of
the exact versions of both the kernel and the driver.  And it's
reproducible outside of mythtv - the same problems occur with xine and
mplayer (both with -vo xv and -vo x11).

Is this a PCI card?  Were you successfully running the nvidia
proprietary drivers against a 2.6 kernel before the upgrade?
