Re: How will this work?
No you don't need a TV. This card will make it like you were watching TV on a TV. so what ever channels you can watch on your TV you will be able to watch on your computer. The sound card part i'm not 100% sure on. i think it will work though.
I think you should look for one for a bit more because the cheap ones usally don't show very good picture quality.
