Just putting this out there in case anyone else runs against it and is curious: on Tuesday, my wife noticed that all of our pay channels (specifically all HBO and Cinemax channels) had become unavailable on our TiVo Premiere XL. All the channels in our FIOS EXTREME HD (I think that's what they call it now) package were intact. Our second TiVo (a regular Premiere with WD expander) was able to read them fine. The behavior would be as follows: Tune to Channel (ex: 899, HBO HD); the screen goes to the Cablecard info screen (grey and white) displaying cablecard info and verizon's phone number. If you press CLEAR to exit, you get a blank screen, followed by about 10 seconds later by the 'you are not authorized' message. Assuming this might be related to the recent change at Verizon FIOS of the copy protection bit, I called their help line. After sitting on hold for a while, I reached a tech who then had me check various settings. He tried first resetting and then reactivating the cablecard. This produced an even more unusual behavior: after pressing 'CLEAR' it would actually show the channel properly for 1-10 seconds, then freeze on that image for about 10 seconds before again determining it wasn't authorized. Verizon then fell back on the belief that it was most likely a TiVo problem, but that if TiVo found no problem, they could try swapping the card. A quick call to TiVo had us look at some information on the card to determine that while it was successfully paired, it wasn't decoding the encrypted channels properly. They recommended getting a new cablecard. A subsequent call back to Verizon arranged for that. Last night the card arrived and after a long call with Verizon, we got it activated and then successfully paired. The card was clearly the problem. No horror story, here. I just wanted to share the information in case anyone saw a similar error. Both Verizon and TiVo had polite, friendly phone support and did their best to help me. Problem solved.
