Advertisements Yeah, except I gave the phone rep my Cablecard ID#. Twice, once with the old card and once with the new. And it still won't work. Maybe the phone reps don't know how to properly configure Cablecards. That's about the only hope I'm holding out in regards to the tech coming. Seven, eight years ago when I first got Optimum they had to send a tech to configure my old Premier TiVo. They used two S cards because back then the guy said that only S cards worked. He was here for hours but finally got it working. Then, after a year I started missing recordings whenever there was a conflict. Finally suspected the cards, swapped the two S cards for an M card myself and it's worked fine ever since. When I got the Roamio I just swapped the M card into it, called Optimum and it came on. Don't know if it's unusual but I've never been able to access my TiVo's Cablecard via their Support Site. It shows an M card in use, but it can't reset or configure or do anything to it.
