[mythtv-users] pixalated live tv images

[Kevin Calvert]

Driver: 361.42
Video card: 01:00.0 VGA compatible controller: NVIDIA Corporation GK208
[GeForce GT 730] (rev a1)

I can try rolling back the driver to 340 and see if that does something too.

I have my frontend installs scripted out and generally just use apt-get to
install everything and noticed I use the 'nvidia-352' package for the
install. I thought that would sticky that driver but I guess that
automatically rolls forward with apt-get upgrade's... which happens
automatically with my frontend restart script.
