I'm running 0.18.1 on Gentoo as well. Also on Nvidia. I recently tried
upgrading to 1.0.8178 from 1.0.6629. That also brought me up to 100%
CPU usage when watching pre-recorded TV, standard definition digital. I
downgraded, and all my problems are solved, Mythtv wise. I only
upgraded to see what difference it made, anyway. Also, it doubled my
frame rate in WoW, so I'm sticking with these.
