I'm afraid I don't know nearly as much as I should about TV broadcasts,
but here's what I do know. I have a plain old coax connection going into
my TV (so no cablebox anywhere in my apt) and I can watch all of the
basic cable channels as well as about a dozen HD channels. The HD
channels show up as subchannels of the respective channel.

So channel 6 standard, shows up as 6-1 HD, 8 standard is 8-1 HD, etc. I
also have a block of about 20-30 digital channels in the 70-something
range that I'm guessing are probably used for digital cable related
stuff like on-demand and the such.

(Pardon my ignorance of all things HD here)
So does the cable actually have two completely different signals coming
across? One for standard and one for HD, or are the standard channels
just coming across as "low-quality" HD?

Normally I'd be just fine with only having the HD channels, but my
favorite channel is Discovery and Comcast most definitely doesn't
provide Discovery HD as part of basic cable. :) I'm just wondering if
there's a possibility that the standard channel might be coming to me on
the wire in some sort of digital format that the HDHR could still pick
up or if I'd be left without it.
