Per, you should be using mythshutdown to determine if/when to shutdown.

mythshutdown -h
Usage of mythshutdown
-w/--setwakeup time      (sets the wakeup time. time=yyyy-MM-ddThh:mm:ss
                          doesn't write it into nvram)
-t/--setscheduledwakeup  (sets the wakeup time to the next scheduled recording)
-q/--shutdown            (set nvram-wakeup time and shutdown)
-x/--safeshutdown        (equal to -c -t -q.  check shutdown possible, set
                           scheduled wakeup and shutdown)
-p/--startup             (check startup. check will return 0 if automatic
                                                           1 for manually)
-c/--check flag          (check shutdown possible
                          flag is 0 - don't check recording status
                                  1 - do check recording status (default)
                          returns 0 ok to shutdown
                                  1 reset idle check)
-l/--lock                (disable shutdown. check will return 1.)
-u/--unlock              (enable shutdown. check will return 0)
-s/--status flag         (returns a code indicating the current status)
                          flag is 0 - don't check recording status
                                  1 - do check recording status (default)
                          0 - Idle
