If you're compiling your own build of MythTV, just get rid of the 
compile-time check that forces the use of the DBus screensaver control 
and instead make it use the X11 screensaver control:

https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythui/screensaver.cpp#L27

Until Stuart writes support for runtime checking of which screensaver 
controller to use, if you're compiling with DBus support, you won't get 
the X11 screensaver support (which allows use of DPMS or xscreensaver), 
nor will you get the OS X screensaver support.
