Advertisements I hope this isn't the toll of doom posting, but this is where I am now. 1. on Wednesday 9/26, Comcast did some "Video on Demand" upgrades in my neighborhood (Copperfield) 2. Prior to that point, I had a working configuration on my Series3 for a year - no issues, no ifs ands or buts 3. After that point, I lost access to a wide range of channels. Pretty much any channel from 72 and up wasn't tuning in 4. I removed the cards from the tivo and rebooted, after putting them back in, I hadn't gained any channels, but I was then seeing the "pairing screen" when accessing those channels. 5. I called their support line for cable cards. They tried to "reauthorize" my cards -- no luck. Support said "swap em out". We did. 6. Set 2 they couldn't seem to activate properly. We then got no channels above 20 -- they said "swap em out". We did 7. Set 3 they can't activate one of the two cards. The other card will "activate", but still won't operate "normally" .. meaning I don't get the unencrypted digial channels. The unencrypted HD channels come in, the channels under 20 are fine -- the rest no luck. They said.. go to another retail front.. get different cards. The techs don't seem to know ANYTHING about the possibility of this being a rollout of Switched Digital Video. Even the good techs don't seem familiar with the terminology. (not the level one monkies, the CableCard techs). I'm still running tivo software 8.3 and my other SD cable box and internet work fine. Does anyone have any ideas how to stop this madness?
