Running mythbackend without tuners is an unsupported configuration.
You will get warning messages about it and may break in some cases (or
in the future) and no one will fix it because it's unsupported. It's
only by chance that it's working for you.
The supported method of running jobs on other machines that do not
have tuners is to run mythjobqueue.
