I have a ATI All-in-Wonder TV card. Its a separate card which is NOT a video card. I run it through my Matrox G550. I used to have a WinTV card, but I have to say the quality of the ATI card is better. HOWEVER, I don't think that is because of the brand (ATI vs. Hauppague), rather its the chip that the card uses. My old WinTV card used a Brooktree 848 chip, and the new one uses a Brooktree 878 (I think those are the correct models). The newer chips produce a better quality picture. Most TV cards use the same Brooktree chip, so you shouldn't have to shop around too much. Mostly what you pay for is brand recognition or added features.
