After getting an HDTV, Comcast surprisingly offered me an late Saturday afternoon appointment two days from when I called and also didn’t scoff at the request for two CableCards for my Tivo Series 3. The tech figured out the Tivo quickly enough for not having used one before - another point for the Tivo interface - and had the HD working soon enough. There seemed to be some missing channels elsewhere, but being an hour late to meetup with friends, I had to leave it for later.
Later ended up being 11:30 at night. The HD channels looked great; you could see every hair, pore, and bead of sweat. Below them, however, was a pretty big gap until the basic broadcast channels; all the typical “cable” channels had dissapeared! Comcast staffs their empire 24-7, but while they sent commands to the CableCards, it didn’t fix the problem. So I’ll be waiting for another tech to come out Tuesday morning and enjoying the new HD channels in the meantime.
