No, I think you understood the question quite well. This was exactly
what I was looking for. I guess I didn't realize that those sub-
channels would provide digital signals that weren't at HD
resolutions. I was trying to find an alternative to having to rig up
a digital cable box with an IR blaster for getting digital channels.
With an XBox Front-end (that means no HD), I was worried I wouldn't
be getting anything useful.
So, I'm guessing if I asked ComCast for an HD cable box, I could hook
it up to my Myth backend, and I'd be able to capture the stations at
480p, even if there is a 720/1080 signal available?

Thank you for that link, I honestly had no idea it existed.
