But this says the config directory is /root/.mythtv, According to the GUI file explorer that is empty (it's set to show hidden files).  If I try to look at via command line, I don't have permission to cd into it.  sudo cd /root  says "command not found," and apparently it's not possible to su on the RPi.  So I don't know what if anything is in that location, or why mythtv is using it rather than  /home/pi/.mythtv/config.xml.

So that is obviously a problem.  I haven't update mythtv for a while.

Alright guys, thanks for all the feedback. Will update the backend.  As for the frontend, I don't quite understand how it got configured to run as root.  I followed the install instructions in the wiki, or thought I did.  I would un/re-install, but not sure how to prevent the root configuration again.
