I need a TV tuner card too, but not to that extent. I just want to watch regular cable TV on my computer, that's it. I've got this computer in a separate room and there's no TV in here so you can see why a TV would be nice in here (my PC).
I'm thinking about getting one of these tuner cards here:
Can anyone recommend or suggest one? Oh wait a minute, I don't have a cable line in this room. How about suggesting a TV tuner that can scan the airwaves?
