Thanks for the report Bert. A couple things:
Motorola DCT5100 product informationFAQ (includes information on firmware versions, etc. -- maybe check what version yours is vs. what the latest is)
It would be great, but I seriously doubt we will get KDKA-DT or WPXI-DT that soon. I doubt he knows what he's talking about on that subject.
Not all the HD channels are actually broadcasting HD all the time. Maybe only WQED was (demo loop?) when you watched. Watch ESPN-HD on Sunday (baseball) or Monday (football) nights and see how that is.
My install is scheduled for Monday.
How could Comcast not think HDTV would go over well? Circuit City and Best Buy and the like have been selling lots of HD-ready TVs the past few years and lots of them have only been used for DVD till now because (like me) their owners haven't gotten around to the initial investment and trouble to get OTA/Satellite STBs and antennas. But signing up for Comcast HDTV is a relatively painless step, so I'm not surprised that there's a lot of interest out there.
