Haugpauge cards and many others do not output to the TV. They are just video capture cards. Your sound card captures the audio. They consume a lot resources and they drop frames. I suggest using AGP video capture cards. Some Nvidia cards from Gainward has a video capture chip that Video 4 Linux supports. I don't know if it will work or not.
The tv out on all video cards are not very good. I suggest using a vga to tv converter from
Focus Enhancements. You don't need any software for it to work. Also some of their better models can handle resolutions up to 1600 X 1200.
For tv watching, have you try other software. Each software has their own way of accessing Video 4 Linux commands. Theres tvtime, mplayer, kwintv, zapping, Xawtv, gnometv, and many others.

If you want us to help you on setting up your video capture card, you need to give more information. I think you need to install the km software for video capture support.
