DVI-red dominates picture

[pacman99]

Hi,
I have a computer hooked up to my HDTV (1080i) via Radeon 9250's DVI port and I get picture but there's some problems with it.
First of all, the picture is a bit shaky unless i reduce it down to 480p, which isn't a problem for me since I don't really play HD content on the computer anyways. It's all SDTV.
The thing that bugs me the most is that the picture has too much red in it. I tried playing around w/ the image settings with no luck. I also tried hooking up my cable stb to it using its dvi output and I get the same problems, interlacing lines and too much red. With component input the picture is fine and displays the normal colours, except of course, with more sharpness and quality
Any ideas what could be causing this? Bestbuy's 'extended warranty' technicians seem to be doing nothing about it. They've "seen this for the first time" on my TV.

Thanks~

I'm not trying to be a smart ass, but have you tried adjusting the color on the TV? My TV keeps the screen settings for each different input. In other words, the color/brightness/contrast settings can be different on each input (antenna/dvd/dvi...etc.).
