I am trying to get a multistream cableCARD from Comcast for my new TiVo Edge DVR. I tried calling Comcast customer support can they can't figure out how to send me the cableCARD self install kit or schedule a technician to come out and install it. In both cases, their computer system wants to link the cableCARD to a Comcast DVR. I tried going into a local serivce center but they didn't have a card compatible with my service area. I am in Maryland.
Not sure if there is something different happening in Maryland, but here in Arizona I just walked into the store and said I needed cable cards for my TiVo Edge and TiVo Bolt. They just pulled 2 from their stock and handed them to me. When I got home I installed them in my TiVo's and then called the number that comes up on the Settings-->Remote, CableCARD, & Devices-->CableCARD Decoder-->CableCARD Installation-->CableCARD Menu-->CableCARD Pairing screen. I then went through the process with them, giving them the CableCARD ID, Host ID, and Data numbers from that screen and I was then set to go. That number is 1-877-405-2298.
