Hi Mike -

I didn't notice your reply.  Thanks for the idea.  It's still doing the
same thing.  I've noticed that my change channel script works before I
start myth, but doesn't work after I start my myth frontend and try to
change the channels.  I have to reboot the machine to see the change
channel script work.
