Somehow, the mythtv backend setup changes /home/jay/.mythtv/config.xml 
from a symlink to /etc/mythtv/config.xml back to a regular file.  I 
restored this file from a backup (192.168.x.x -> localhost) and the BE 
now works again.  This still does not help get the new FE to work.

Why are there so many config.xml files?  Which one do I use?
