TV-out varies alot on NVIDIA powered cards, each OEM gets to choose what TV out converter chip they use.Are Nvidia cards any better?
Make sure it's a Made by ATI not Powered by ATI card. 'Powered by' means a third party OEM made the card, and used whatever TV out chip they felt like.on a side point I would have thought the TVOUT on the radeon 8500 would be pretty damn good- what gives?
Also, are you using a S-Video to composite adapter? Those things take down the quality compared to a card that natively outputs Composite.
