mplayer does the same thing as myth.  CPU as close to 100% as the
other processes allow, black screen, unresponsive, locked up.  I could
not even kill it, had to restart X.

I added Option "NvAGP" "0" to the video card device in xorg.conf and
it works, at least on one file that previously did not work and it is
playing in XvMC with about 40% CPU, which seems good.

So, what do you think happened?  I did not change my xorg.conf file
after the upgrade.
