I have a DTC-100, and am only using it right now to pick up two Time Warner HDTV channels (HDTV and CBS). I am waiting for Time Warner to receive additional HD cable boxes. I am not using it for DirecTV. I have a couple of questions: 1. Is there any way to receive firmware updates without DirecTV, and more importantly, 2. Since I have a cable line hooked up to the DTC-100 (to pick up the 2 channels), I was wondering why it does not pick up all of the unscrambled cable channels. Am I doing something wrong?
