Does anyone own or have experience with any TV tuner cards? We recently got U-Verse and my room has a wireless unit for the TV. What I'd like to do is get a TV tuner card so I can just move the wireless unit between my computer and my room so I can watch TV in either place (there isn't a TV in the basement where my computer is). I'm just not sure on what brands are good or what specs I should be looking for etc.
