[mythtvnz] Green screen .. help please

[Simon Cantem]

Hi Bernie,

If you're still running the 173 drivers this sounds like maybe it's related
to the problem you're having:

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173/+bug/199975

I'm running 177 on a 9600GT without any problems, maybe give the new drivers
a try if you can.

Another thing to try is checking your hue:

$ sudo apt-get install xvattr
$ xvattr -a XV_HUE
Found Xv 2.2
XV_HUE = 0

if that returns anything other than 0, try doing the following command and
it should set it to zero:

$ xvattr -a XV_HUE -v 0
Found Xv 2.2
XV_HUE set to 0

Cheers,
Simon
