[mythtv-users] Matrox G400 DualHead - Live TV is squashed

[Matt]

I'm going to assume that scheduled recordings have the same problem.  If 
they do, then I believe the problem that you are having is caused by the 
overscan settings on your TV capture card.  You can also test this 
theory by playing the recordings in mplayer,  if I'm right the 
recordings will have a border in mplayer as well.

I like my G400, the only problem that I have with it right now is with 
the color/saturation; red is way too saturated
