I liek the ATI radeons for TV-out. Ive got a 7500AIW, and I don't know if it's the card itself or the TV or mystical alignment of the forces, but it looks real nice for videos, 3d, games and mame. It's a little fuzzy for regular windows but I usually leave it at 1024x768 so that's gonna happen
I also have a voodoo3 with tv-out that is OK and works in a pinch
