If you look at the upstart configuration, it depends on the non loopback 
network being up for the backend service to start:

start on (local-filesystems and net-device-up IFACE!=lo and started 
udev-finish)

I believe the idea is to ensure that the backend is listening on all 
interfaces when it starts so that remote clients can connect.
I do recall some workaround is to just configure a dummy static eth0 
interface that always comes up so the script can get on with it, or you 
could hack that section out of the upstart config 
(/etc/init/mythtv-backend.conf).
