Mythfrontend uses the config.xml file under the home directory of the
user it is run from.  In my case, I install Mythbuntu with a user
"stephen" as the default (autologin) user, so mythfontend uses
/home/stephen/.mythtv/config.xml.  If you want to have only one
config.xml file, you can rename or delete that file and link it to the
main config.xml file:

cd /home/stephen/.mythtv
mv config.xml config.xml.orginal
ln -s /etc/mythtv/config.xml
