I have a much simpler approach than Mike. When the mythtv user logs in I
run the Perl script below to another script which ends mythfrontend. You
need to use xscreensaver since gnome-screensaver doesn't seem to work
with MythTV (anymore).

The script which gets executed looks like this.

--------------------------------

In case a show is paused it adds a bookmark, goes to the mainmenu and
exits mythfrontend gracefully. If that fails, mythfrontend gets killed
the hard way. I had to add a delay of two seconds between each key
press, otherwise some of them wouldn't be executed.
