Videocard problems

I want to use my second pc for an arcade machine, but there seems to be a problem with the s-video output on the videocard (128mb radeon 9000 pro). Whenever I hook the pc up to my tv, the picture is black and white and the screen keeps moving up real fast (like a bad connection). This isn’t just in windows; it happens during POST as well.
This is my tv:
Is it possible be hook the videocard up to a tv without using the s-video output?

Sounds like your videocard is set to output in PAL while your tv can only handle NTSC or the other way around.

hmm…anyway to fix this?

Snoop around the displays control-panel, you’ll likely find some way to change it there if this is indeed your issue. Can’t be more precise than that as I don’t use Windows.
