Stephen: I noticed the database change after sending the email and
poking around some more. I like the idea of going to the Guide and
using M > Watch!

Peter: Yes, both tuners have separate lineups that only contain
channels they are able to tune, but the backend still tries to get the
HDHR to tune a channel in the HDPVR lineup that is not in the HDHR
lineup.

and I'll cross my fingers this gets resolved!
