I had 'partial lock' reports when I was trying to set up a dvb-t2 tuner
that I was able to cure by writing network and transport IDs into the
dtv_multiplex table in the DB. There didn't appear to be any other way
of getting them there. Obviously this isn't exactly your problem but it
sounds similar. Try mythbackend -v channel and see Ticket #10217 or
