The top profile for Blu-Ray is 36 megabits per second, and that is
not used on most titles. Over-the-air HDTV is 19 megabits or less.
Cable HD channels are often only 12-15 megabits per second.

Chris glances off, but doesn't quite say, that cable providers are prone
to *reencode* OTA HDTV, leaving cable subscribers with a worse -- sometimes
a *substantially* worse -- picture than they'd get from an OTA antenna.

Well, the OTA providers are doing it to the network feeds first, so I
don't see focusing on the cable providers doing it to the OTA providers
as the sole source of quality issues.  The OTA providers also reencode
to add bugs, weather/breaking news crawls, etc., and they don't always
do a good job of that before feeding the signal to the statmuxer.

I don't speak for anybody but myself - that's enough trouble.
