I have a friend who would like to use his computer that we are building for home theater. He would like to make it wireless is that possible? I mean if we get a wireless linksys router can he do that and still use it for home theater? There are two other important things too. 1. If he outputs the video image to the toshiba hdtv is burn in going to be an issue if he surfs the internet? 2. What sound card should he get? Thanks so much for your time in this matter.
