I would presume that the EPG follows the resolution of the output
setting. But that may not be the case if your theme, in effect,
contradicts the resolution of the output hardware. Myth menus's may not
be affected, but the guide is not a 'unitary' sort of thing. Just a

THAT is really weird. You may want to try shutting down the frontend and
backend, then ssh'ing in to establish a connection. Then restart the
backend and frontend, and see if you can crash things....with the idea
of seeing how far into the process list (ps -ae) the crash reaches. As
noted, when I freeze the frontend, ssh continues to work, even though it
is the last process.
