Happened in Houston a couple of years ago. The HD Homeruns work just fine with my rooftop antenna. I could never stand QAM Cable with Comcast, they moved things around so much it was pointless. I like having a guide. Get a cablecard tuners my brother has both the SD HD Prime and Ceton tuners. I have a Ceton.... he has had a world of hell with the Cetons. He loves the Prime although he still uses both. I would buy a Prime if they ever shipped a 4 tuner as once promised. My Ceton works but it needs the most pristine signal possible.
