We have TWC for TV service. Last night I found that among the channels our digital TV channel scan had found was NBC on 83.3, and there was the super bowl in high def, full screen! At around actual kickoff time, the screen went blank, and we had to switch to channel 6 and watch in low def. What happened? Some other HD channels still were functioning.

Somewhere I was told that the cable network acts like a giant antenna, and that the TV was picking up the over-air signal in the channel scan, but I don't know if that is correct, given that the cable is coaxial and is supposed to be free of outside interference. Did TWC do something sneaky?
