To be honest, I'm new to digital cable, so I'm not completely familiar with how CableCards work. I've only had it for a few weeks, and I specifically signed up because of the Roamio. I had a tech come out and give me a card for my old TiVo so I'd have it when I finally got my new Tivo in, that way I could just call and pair and wouldn't have to wait for a tech at that time. Anyways, the card didn't give me any problems in an old HD unit the whole time I had it in there. So then I called to pair it with the Roamio this past Friday and everything was great for 24 hours, that's when I lost my channels for the first time. As with everything (computers, phone, etc) I tried restarting the TiVo first and they came back and everything was fine. Since Saturday afternoon I've lost them a total of five times, three times I had to restart, but twice the channels came back on their own after I received this message on my screen: CableCard Error: A technical problem is preventing you from receiving all cable services at this time. Please call your cable operator and report error code 161-17. I'm going to call and have a tech come out later this week, but should I prepare myself for this being a TiVo issue? I'd like to figure it out ASAP because I purchased it from Best Buy and their return policy is only 15 days. As I said before, I'm new to CableCards so I don't know if they "go bad" after being swapped out. Thanks for any advice!
