[mythtv-users] Hooray! I've got a...blank screen?

[blake at kingdomrpg.com]

Knoppmyth on an AMD 2400, GeForce ti4600, 1G Ram, 120GB HD, Hauppauge PVR
150. I have S-Video coming from a digital cable box into the Hauppauge and
S-video going from the GeForce to the TV. The S-Video input is selected on
the TV.
I select Watch TV, and everything goes blank.

Stuff appears to be happening--the hard drive is flickering--but no image
on either TV or monitor, and I can't seem to stop anything.

I'm going to try the edits suggested earlier for the nVidia....
