For the TV Tuner card, I recommend a PCTV capture card. It has a coaxial plug, a composite plug (which that ATi one doesn't have), and an S-Video plug. I got mine for only about 80 bucks, and it gets a pretty good picture. It's not TV quality, which that ATi one may be, and there's a downside. But I use my composite plug A LOT, and since that one doesn't have it, I would recommend getting one that does, be it a PCTV or not.
Just a thought.
