Feedback on current master 477ddfd in DVB-T/T2 land (UK Freeview):  I 
re-scanned using 'all known transports' and the new option, and saw no 
problems.  One DVB-T2 transport reported 'possible' channels; I 
rescanned that transport and they they became 'probable'.  The log is 
now easier to understand, and showed no actual change.  Boringly, it 
'just works' - at least for me.

I don't understand the ATSC subtleties, but I would expect that the 7 vs 
35 or 12 vs 35 frequency problem could be solved by deactivating the 
unwanted transport in the transport editor.
