Why would the brick happen? Wouldn't you just add the new DTV conversion box?
I don't pay for cable tv because most of the programs are reruns or not worth watching. I have tv's in my bedroom, kitchen and livingroom that are relatively new but analog tuned. I also have DVD recorders that seemingly will become bricks when the analog signal dies. Are there DVD recorders or DVR's with digital tuners being made for receiving broadcast signals?
