not if you buy a over the air HD antenna to go with it. you hook up the antenna to the tuner to your computer that eventually feeds to the TV. you get roughly 30 channels in the US, out of that 10 are HD, all the major network channels. and with MCE, you can record and rewind shows.
I don't think you read my first post. I covered the amount of channels. Not everyone lives in cities where they get tons of channels.
So this would be a service I could use, and its cheaper than paying for very restricted cable. But I don't think it will ever happen here, they aren't going to put up their super multi antennas in this region.
