Advertisements Hi. I have had an HD Tivo for 3 weeks, and we still can't watch premium channels. Comcast says it's a TIVO problem, or that they need to replace the cable card (For the 12th time!), and TIVO says it's a Comcast problem. I don't know what to do. I've had so many issues with this TIVO from day 1 - trying to get the cable cards to work, not having any stations, etc., but we've now had live TV for 2 weeks without premium channels. When I switch to a premium channel, I get one of 3 things - either a gray screen, a frozen picture on the premium channel - it tunes and then freezes, or the screen that says contact your cable card provider. Sometimes I get all three of these things on one channel...(not at the same time). I could go into the channel and have a gray screen. Back out and go back in and have a picture that freezes, and back out again and go in and get the cable message. Does anyone know what the problem might be? I'm using an M-card, because Comcast could not get the second S card to work in our TIVO. They claim that everything is paired correctly. Tivo says it's not. I don't want Comcast to switch cable cards because the last time they tried that, I didn't have TV for a week. Something interesting...when I didn't have any live TV, and I had the gray screen that I have now on my premium channels, I was still able to record shows. When I went to watch them, there was nothing there....just a gray screen. Then, a wekk later, when I got live TV back, I went back and was able to watch the previously recorded shows that were gray screen, and now I had full video. Very strange. Does this indicate the problem is a TIVO issue or a Comcast issue?
