I mean changing to a channel that is not defined in the database.  Do
you do that?  I just wasn't able to do it on my system when I tried it
last night, but like I said, maybe my config is messed up.

Yeah, I looked into the settings table in the database and found the
"TVFormat", "VbiFormat", and "FreqTable" keys.  Those control the
behavior of the card (this is version 0.11).  (though, arguably, this
should be set on a card-by-card basis or even channel-by-channel, but I
guess that wanders off the topic of this thread)

I think the problem the guy was having was that there are no channels in
his database, so MythTV won't go anywhere.
