I'm trying to provide some extra information regarding an older post I found:
- mythbackend runs on every MD created in the system, even MDs that don't have tuner cards. In my case, I have a tuner card controlled my the core, but many extra MDs in the house that don't have tuner cards, and running mythbackend on them wastes resource and memory (they are thin clients)
- there is apparently no way to turn this off via the admin, even when selecting that an MD has no tuner card (please correct if I'm wrong)
- an older post suggested to disable the script /usr/pluto/bin/Restart_MythtvBackend.sh on every MD where you don't want mythbackend to be running (for example by renaming the script to something else)
- for me thsi was not enough. In addition I had to run:
update-rc.d mythbackend remove
on each MD
Hopefully this helps someone. Not sure if it would have a place in the wiki since it's kind of a hack...
