If anybody remembers, my Tivo S3 was the one that apparently had its HDMI outputs fried in a lightning storm last month and I finally did an advance exchange with Tivo. So... I read the threads on how others had been able to swap the cards into a new Tivo without the truck roll and I called Comcast (of Chesterfield, VA) to tell them that I had to replace my Tivo under warranty and needed to set up my cablecards on the new Tivo. I followed the Tivo instructions to a T. I inserted the first card, waited until the grey screen came up with the information, gave that information to the Comcast person who then "hit" the card. I checked channels throughout the range and everything looked good. I then did the same thing with the second card and everything looked good too. Seemingly satisfied, I got off the phone and started watching TV. When I got to ESPN HD (channel 242) I had a great picture for about .7 seconds and suddenly the "Call your Cable Company" gray screen came up. The same thing happened with TNT HD on channel 249, though it took several seconds to get the same effect with TNT HD and one time I was able to watch TNT HD for several minutes before the "call your cable company" gray screen came up. So I called Comcast again (these people have never heard of a DAC operator, btw) and had them hit the cards again. We did it several times and it never resolved the issue. I looked through the Tivo website and saw that sometimes the SA cards take a while to get fully authorized, so I went to bed. This morning, have the same issue. I tried to get the person to give me the technical support that the technicians call when they do a truck roll, but they refused. Any ideas of what else I can have Comcast do? This is the rare instance in which I KNOW it's not the cards, since they were working in the old Tivo up until I swapped it out last night. If I have to do a truck roll, I think I'll just use it as an excuse to switch to FIOS rather than deal with the idiots that Comcast sends out.
