If you copy /usr/share/mythtv/devicemaster.xml to
/home/mythtv/.mythtv/devicemaster.xml and edit it there, that should
allow you to change the names that show up when selecting backends.

I believe that it is possible to use -O to override settings that are
in the settings table if the program does not have a native way of
changing them.  So something like this might work:

-O RunFrontendInWindow=1
