That's right. The fact that one card is analog and the other digital
isn't important; if you had two analog cards with different sets of 
channels you would need two data sources too. You wouldn't be able to
omit the tuning data for a channel on one card only.

True, the grabbing situation isn't ideal. You may have duplicated data
in the db (I'm not sure) but that doesn't seem too bad.

Sounds right.
