Well, I hate for my first post on a board to be a rant, but here goes anyway... Executive summary: Trying to get an M-card working in my new THD, and Comcast is as useless as ever... - First visit, guy was three hours late on his three hour window, meaning I had been waiting for him for six hours. Installs cable card, gets some channels working, claims the others will kick in within 8 hours or so. I naively believe him. - Next day, still no premium channels. I dig around in the cable card menus and find that the card is not even properly paired. My wife calls Comcast, wastes another hour on the phone, only to be told "we need to send a tech out again". A supervisor is supposed to call her back, but never does. - Fast forward a couple days, tech shows up, saying things like "oh, a cable card, you're in for a ride", and "I don't know why they even use these things". And this one "Well, Edie is the only one on the head end who really knows how to make these things work, and she's on vacation for two weeks." He proceeds to spend three hours on the phone with them, manages to get the card paired, but still no copy protected channels are authorized. My wife calls the Tivo cable card hotline, and puts the tech on with them. This quickly degenerates into a useless pissing match about whose fault it is. After three hours, she's had enough and kicks the tech out. - Another call to Comcast to try to speak with a manager gets another "we'll have someone call you back..." - Although I am quite convinced the problem is solely with Comcast, Tivo's cable card hotline is, unfortunately, borderline useless as well. A second call to them was very short and ended with basically "well, we can't do anything for you". Might be true, but I thought the hotline was there to help work with the cable companies. At this point, we're pretty much ready to cancel our cable service outright, box up the THD and take it back, and cancel the one non-lifetime Tivo account that we set up for it. Which really sucks, because we love Tivo (had them since the very first units were available like eight years ago...). But I'm having a hard time justifying paying for services when we're getting treated like this (especially given that other media options like Netflix, bittorrent and others pretty much just work). Soooo.... If we decide to give it one last gasp, does anyone in the Potomac Falls, Virginia area have any suggestions as to who to call, what to say, or whatever to try and get this resolved?? Any help would be appreciated. Thanks.
