hmm, undrar om de verkligen skall vara tomma:

In mythtv-setup, go to the 6th page under the 'General' settings. This
should be a page titled 'Backend Wakeup settings'. At the bottom, you'll
find "Sleep Command" and "Wake Command". You want to configure those
commands on each slave backend that you want the master to be able to
shutdown and wakeup on demand for recording.
