After some trial and error and comparing the original mythbuntu 14.04.1 
configuration (which worked properly) with the upgraded configuration, I 
found the difference.  In my upgraded configuration, I needed to 
configure the Zoom setting on the Video Playback to V.Fill.  This is 
what the default was for the new 14.04.1 install.

On another note, mythfrontend now crashes when I exit from it after 
playing any videos.  If I exit mythfronted immediately after it starts, 
then it does not crash.  This is NOT related to the Zoom setting, but 
something else.  The pop up reports that mythfrontend crashed with exit 
code 134 and will be restarted.
