So, after following this forum closely for several months, I finally took the plunge and bought a Series 3. I also bought a 42" plasma (Panasonic 42PX60U). The TiVo arrived first, on the Wednesday before Thanksgiving and I set it up on Sunday as soon as the relatives had cleared out. The TV was scheduled ot arrive the following Friday, and Comcast the day after to install the cablecards. Still had to live with the old CRT TV for a week, so I went to the local Radio Shack and bought a $30 amplified antenna so I could pick up the HD signals. For the record, I live in Chicago, in the city, about 4 miles north of the Loop, and fomr the third floor windows can see the Sears Tower and John Hancock, where most of the TV transmitters are located. TiVo setup was fairly straightforward. I hooked up the TiVo network adapter and it found the network immediately and had a strong signal. Hooked up the antenna and the cable. So far, so good. Much to my surprise (and delight) the antenna picked up almost all of the major HD boradcast signals (plus a bunch I had never even heard of). One exception - channel 2-1 (CBS-HD) did not come in. TiVo seamlessly integrated the OTA and cable channels into a single lineup. Nice. For a week, this arrangement worked great. I still had the S2 and cable box, so I could switch between the two if needed. HD looked good even on the old CRT. The TV showed up on Friday. Easy to install and hook up. Great picture. OTA broadcasts had a few dropouts, and sound didn't seem to be quite exactly synchronized on one of the tuners, but I was willing to hold off till the CC's were installed before complaining. Comcast showed up on Friday, at the very end of their 4-hour window. Then the fun started. First of all, Comcast charged me $43 for the truck roll. When I had set up the appointment, I was very clear that they were installing to a Series 3, to send me an experienced tech, and bring extra cablecards. The tech shows up with exactly 2 cablecards, and hes has NEVER installed a cablecard, much less one in a TiVO. When I look at the work order, there it is "...installing to a TiVo Series 3...". guess he can't read his own work order. Says he told his supervisor that he'd never done it, and they sent him out anyways. So, using the instructions taht came with the TiVo aplus lots of useful info I'd printed off the forum, I went to work (he just sat there quietly - I wasn't about to let him touch my brand new S3). In went card #1. a few minutes later, the info screen comes up. He calls dispatch. they put him on hold. The hold message says he should go to comcast's web site for faster info. Funny - they make their techs listen to the same crap we have to listen to. He calls back several times - they hit the card. Some chanels come up. Not many. HBO is missing. As are most expanded basic channels. HD is working. He calls dispatch. They hit the card again...and again... The tech starts calling his buddies for help. They are too far away and don't have a clue. He suggests we try CC #2. Against my better judgement, we try CC #2. It goes in. Error 161-4 comes up. Thanks to this forum, I know that that was not a problem. He calls dispatch and they hit the card. And it works! All channels come up. And I scrolled through almost every one. With dispatch still on the phone (this tech seemed to know what he was doing) he hits CC#1 again. We go back to CC#1. And it is also working!!! The tech hands me the work order and asks me to sign. Not so fast, I say. I scroll through the remaining channels on CC1 (yes, this does take a while, but I'm paying for his time, and I am not letting him off the hook so easily). Eventually I am satisfied that both CC's are working properly and all the right channels are coming in and audio is synced up. Then I start guided setup again. Since he's never seen a cablecard, much less a TiVo, he thinks it is all part of the CC process (a touch of evil revenge on my part....) I eventually let him go to his next gig. Total time: 55 minutes. And fairly painless, considering the stories I've read here. The next day, my wife calls Comcast and complains about the tech's lack of knowledge. Says that he was very polite, pleasant and friendly, but had no idea what he was doing, and that I had to do all the actual work. She doesn;t understand why she has to pay Comcast $43 when her husband did all the work (first time she's ever accused me of *that*). Comcast apologizes and refunds the $43 for the truck roll. All in all, not a bad experience. And thanks to EVERYONE who has posted to this forum - without it I would have been lost.
