Being offline might be your problem.  For me (using .15 still), whenever 
I have no program data for the current day (happens frequently when 
Mythfilldatabase first deletes the days data then the download fails), I 
can't change channels.  Appears if there is no program data, it can't 
change.  I fix the issue by running mythfilldatabase and repopulating 
the program data.  Sometimes I have to restart mythbackend before it 
works again.  If you're offline, you might want to try manually 
inserting data if you're comfortable with sql or else finding an 
internet connection for that machine.
