I am using the Nvidia proprietary driver (current AMD64) with Myth.
Anytime there is some panning, I get a horizontal shearing of the
video. I have enabled glx vsync in nvidia-settings. I have tried NO_XV=1.
I have an AMD64x2 6000+ with Nvidia 630a/GEForce 7050 and I am using
HDMI output. GLX gears performs at about 2500.
Should the mythfrontend be looking at /dev/dri? This makes me think
nvidia-settings does not do anything useful for me. It does retain the
settings when I invoke it again.
