Now I am really confused.

That worked, even though the config.xml was identical in both locations.

I just checked to see if the permissions were the same for both files, and discovered that one is a soft link to the other.

$ ls -l

lrwxrwxrwx 1 mythtv mythtv 22 Jun  7  2014 /home/mythtv/.mythtv/config.xml -> /etc/mythtv/config.xml


I don't understand it, but mythbackend is running again.

Myth front end is no longer going into the infinate loop attempting to find the backend. I tested live TV, and that worked.

Mythweb is also working again.

Thank you.
