OK, I think I'm OK now. I shut the box down and the cable had come off
of the card input. I had moved the box recently for another reason and
it must've slipped off. Once I connected it all back up, I could tune
to both portions of the card (Analog and Digital). Analog looks like
crap, but it always did. It looks fine in TVTime, but not in Myth. Oh,
well, I'm not worrying about that for now.
Thanks for the advice!
