Advertisements I've had a Roamio and Medicom cable working great for 6 months. In the last few days, 4 HD channels have become "unauthorized" or bring up the cable card screen (ESPN, ESPN2, FXX, etc.). I've changed out the cable card, rerun guided setup, rebooted, been walked through a dozen things by Mediacom support. Still no luck. All other channels work fine. Mediacom Man is supposed to "investigate" and call me back later, but I have my doubts. I don't have another TV to check. Any ideas or suggestions? Thanks.
