Below is the mythfrontend logfile output. It's clear that something is going wrong, but I'm not sure what or how to fix it. I've tried both the 'internal' and 'libmpeg2' - both give the same result. Currently my system is set to use the full screen for both TV playback and the GUI.  Thanks for taking a look at this!

Check your mythfrontend logfile output using the playback and file log
options (or run mythfrontend from the shell) and check which MPEG2
decoder you are using - there is standard and libmpeg2.

Are you specifying different resolutions for the MythTV GUI and
 playback?
