Mythbackend certainly thinks the tuners are OK - it is able to talk to
them and issue them commands and see responses. But that does not
mean all the settings are correct for them to be able to record.

It depends on what your LNB is. Simple dishes in Europe would
normally have a dual oscillator LNB, for which "Universal (Europe)" is
You also have to have set up the LNB settings - the two local
oscillator frequencies and the frequency at which the switch is made
between the two local oscillators. If you have VLC working, you must
have put those same settings into it.

When running mythbackend, you might like to add another option to get
more logging about the tuners:
mythbackend --loglevel debug -v record
