In your xdpyinfo output:

which shows you have your screen configured with about a 14:1 aspect 
ratio.  I'm sure your monitor isn't 14:1 physical dimensions, so you 
need to fix your X configuration.  The Display Size link will give you 
some info, but where/how you change for your distro is something you'll 
likely have to get from others using your distro.

Fix that and MythTV will work like you want it.  (In other words, MythTV 
is doing exactly what it should do at this point.)
