Advertisements I have a Tivo HD and I am a Comcast subscriber in the Coatesville PA service area. I have reboots and the 3 hour wait green screens suddenly. Before I replace a drive, how can I tell if the cable card is paired? I don't care about my current recordings, so If there is a way I can tell if I can "Instant Cake" a drive that would be great. Thanks. I did search for an answer, but I don't see it.
