Alright I'm trying to get my media box hooked up to my TV. It has an ATI Radeon 8550 in it. Here's the settings I used for the TV:
1024x768 res, 32 bit color, 60 hertz, SVIDEO input.

When I try to hook it up to my media box or my sig rig, (ATI Radeon hd3870) The TV shows the picture but the picture keeps scrolling. Then I tried it with my friends laptop (Intel Integrated GFX) It works fine. What gives? I'm guessing it's the drivers, so I'm going to try that in a bit. Any other things I should try?

I would venture to guess that the two ATI cards are fighting over the drivers. Isn't there a way to utilize the 3870 instead?
