The only thing I can suggest is that MythTV is not changing it, but 
something else is in response to MythTV's asking for a window that's 
larger than the current display size or something.  Go into Appearance 
settings and set your GUI width and height to 0 and see if that helps.

But, again, MythTV doesn't change X display modes, except with the 
setting above, so if you've disabled that, something else is to blame.  
I don't know what would do it, though.  It's likely something to do with 
your video driver and/or the fact that you're using Xinerama (or one of 
its kind) and video drivers don't like for video to be anywhere except 
the first screen...
