[mythtv-users] LiveTV (only) Broken After Upgrade

So I was setting up another MythTV frontend box for my backend server
running 0.19, and I accidentally grabbed the latest SVN snapshot
rather than the 0.19 branch. The remote frontend did all kinds of
interesting things to my backend. And I did not back up my database
(of course). That resulted in a chain of events that ended in me
throwing my hands in the air and upgrading the backend to the latest

Besides, I really like that cool fade thing MythTV has going between
menus. ;-)

Anyway, LiveTV broke. Yet, scheduled records still work! Here is a
timely portion of the log:

2006-03-14 00:27:19.068 TVRec(1): Changing from None to WatchingLiveTV

                        Most likely, your DefaultTVChannel setting is wrong.

I checked to see if the Colbert Report was being recorded, and sure
enough, there it was. So that gives me hope that this is a minor issue
that can be resolved with the right magic incantation.

Any advice on surgically repairing my installation so that LiveTV
works again?
