That sounds like what I was getting running with VAAPI on the old
Intel drivers on my laptop (with XFCE4).  The whole of X was locking
up when I exited from playback.  I could use Ctrl-Alt-F1, login and do
a "restart lightdm" to restart X and then it worked again.  So it is
probably not a mythfrontend problem, but something to do with the X
setup or the video drivers when running Ubuntu 2D.  My problem was
solved by installing later Intel drivers from 01.org, and changing my
"Paint engine" setting (Setup->Appearance).  These days "Paint engine"
probably should be set to Auto, but if you are like me and have been
upgrading from earlier versions before the Auto setting was available,
it may be set to something else.
