Sounds like some other program is listening on one of your backend's 
control sockets.  First, stop both the backend and frontend.  Next run 
the backend setup program again and make note of which ports the backend 
is configured to listen on (the defaults are 6543 and 6544, but if 
you've modified them even by mistake..).  Now (with the backend still 
shutdown), run (as root) 'netstat -a -p -n' and look for a program 
that's listening on one of those ports.  Based on that information, 
you'd want to change the configuration of MythTV or of the conflicting 
program so that they don't listen on the same port(s) anymore.
