Advertisements I have Digital Preferred with Comcast, and my TiVoHD won't display 3 channels associated with that tier of service: ESPN Classic, MPlex, and Flix. I get the gray "please contact Comcast" screen when I tune to these channels, just like you'd get if these were premium channels. All the other channels work just fine. The CSR says the CC is fully authorized. What could be wrong, and what should the CSR look at? I tried calling customer service but of course the CSR claims nothing is wrong and everything is working perfectly.
