My test box has two single-tuner devices, one DVB-T only and one 
DVB-T/T2/C capable, although I don't have cable.  The transmitter has 6 
DVB-T and 3 DVB-T2 transports.   mythtv-setup shows two Video Sources, 
one for each device, and I do scans (for All Known Transports) with 
each.  It seems to be simplest to delete all channels for that Video 
Source before any scan; otherwise conflicts may be reported and I (at 
least) feel confused.

I have found that the initial transport list can be mostly populated by 
entering the frequency of my main DVB-T2 transport and enabling the 
automatic links. YMMV.

Once all this is done the scheduler selects the right devices.  I'm not 
absolutely sure that I need both scans, but it all seems to work.  For a 
main system you would probably want more tuners.
