Toss your ATI TV tuner away, and pick yourself up a Hauppauge WinTV PVR card. I've built quite a few machines with the Hauppauge WinTV PVR 150 tuner card (which is an MPEG2 card btw) running Windows MCE and Vista Home Premium/Ultimate, and the card has worked flawlessly every single time... except once (sometimes the card doesn't like boards that use VIA chipsets). Just be careful of which card you get as there are different versions of the 150. The one I usually get is the regular OEM card, which is a full height card, comes with 1 coax connectors (sometimes 2), red/white/yellow composite connectors, and an S-Video connector, doesn't come with an MCE remote, and you can get it for less than $70 US / $90 CAN (NCIX, for instance has it here in for the
US, and here for
CANADA. There's also a retail card, however Hauppauge is known for 'switching out' cards for a different model whenever they are short of stock, and in this case the model they switch out for, the 900, is a POS. Not always the case, but sometimes.
An alternative would be the
WinTV PVR 500, which is a dual-tuner card.
