Thought I would reply with my experience with Comcast in the Peoria, IL area on Saturday. The tech rep showed up in the early part of his 1-5pm window. He brought 2 M cards with him for the tivo which I was glad to see they actually had M cards here. He said he hadn't done a whole lot of cable card installs on Tivos, only about 3 in the last year around here. He said the cable card technology was getting better, but that they were still having lots of problems with installing cable cards in actual TV's. Usually this was because the TV's needed firmware upgrades to get the cable cards to work. Of course comcast doesn't know about this, and neither do the users which cause lots of frustrations. Anyway, the guy put in the M card, and I went ahead and ran through the tivo menus according to the instructions as he thought I would know more about where I needed to go in the menus. He copied down the codes he needed that were picked up by the tivo, and went outside to call in the numbers to a tech. Once he came back in, we ran through the guided set-up again, and it was working fine picking up all kinds of HD channels and everything I needed. I was even getting some HD stations that he didn't think I should be getting which was a bonus for me (he could care less if I was getting more than I was supposed to). Total time was probably about 45 minutes, but most of that was spent with him on the phone or downloading the new guide information. No problems really to speak of other than my analog stations being a little choppy at first, but a quick reboot of the tivo fixed that. The best part is that I only technically have 1 cable card now, so Comcast shouldn't be able to charge me for that since the first one is free. I'm thinking that slowly but surely cable card installations are becoming more common and the technology is catching up to avoid some of the earlier problems.
