As an update, here is the output from mythbackend when I try to use the 
channel up or channel down buttons:

Error, couldn't find any available channels.
Channel: ' ' was not found in the database. (this isn't a typo - ' ' was 
empty)
Most likely the default channel set for this input
(1 tuner 0)
is setup wrong
Couldn't find any channels in the database, please make sure your inputs 
are associated properly with your cards.

I ran mythfilldatabase as the mythtv user and it exited successfully.  I 
don't know what's wrong :(
