I just rebuilt my HTPC, with a Sapphire Radeon HD 4670 - 512MB card. The very first time I connected the S-Video cable the TV produced a B&W scrolling image of the computer's output. And since has never showed anything except a black screen. It doesn't show the POST, or any part of the boot process. I have a LCD hooked up temporarily to t-shoot. Normally all of my useage would be via RDC or playback via s-video to my TV.
I've tried just letting Windows detect the card and use it's drivers, the ones that came with the card, and finally I have these installed:
http://game.amd.com/us-en/drivers_catalyst.aspx?p=xp/aiwradeonx-xp
Catalyst Software Suite v8.12
ATI Multimedia Software v9.16
When I look at the displays via the ATI software, it basically doesn't look like it recognizes the TV is hooked up at all. My previous build had an old ATI AIW 128MB card, that I didn't have to do anything to connect the s-video.
