If you want to watch TV on your computer, you can get an ATi card that has Video Input Video Output connection (VIVO), you should be able to use S-Video or standard Audio/Video cable, then get a TV software like BeyondTV, and using an audio jack connector (Like the ones used on headphones)connect it to the Audio Input of your sound card and you should be fine. That What I currently do to watch TV from my Dish Network, I use the S-Video cable connnected to my S-Video socket on the videocard and then I use a Standard Video/Audio cable to Headphone jack cable converter, and I connect the White and Red audio plugs in that cable, and then I plug that cable to the Line In of my X-Fi audio card, and everything looks and sounds good. That's because my card as far as I know is not able to process audio. But if you get a All-In Wonder videocard like the Radeon 9800 All-In Wonder you should be able. But if you want to save money, why you just don't buy a TV Tuner card?? It comes with everything you need for audio and video.
