I'm not going to mark my mythtv problem SOLVED until I'm sure that
mythbackend is running stably.  It seems to be working for now.  The
problem is that I can't change channels in mythfrontend.  I'm watching
live TV and I'm hitting the Up arrow key (as specified on mythtv's web
site, but the channel is not changing.  What's worse is that it seems
all that's on the one channel I get is infomercials!  How can I fix
this???  I ran mythsetup and and went to the Channel Editor.  There were
no channels defined.  I wanted the click the Scan For Channels button,
but I couldn't figure out how to get to it.  Also, (I think it was in
mythfrontend) I set the GUI to appear in a window instead of full
screen.  It turned out to be not what I wanted and now I can't find the
option to get the full screen mode back.  Help!
