I think only having one multiplex that supports DVB-T2 limits the HD channels on Freeview. In the short-medium term it would be preferable if all (or at least one) multiplexes except PSB1 & PSB2 migrated. Then eventually just one of these two remaining as DVB-T to provide a basic/legacy service, with the other having national capabilities.

But the Vaizey plan was to,make PSB emit HD only in all platforms
Which moves the technology of tv forward by (sensible) intervention.
As I mention elsewhere a sensible solution was a PSB regional mux ..
(roughly what PSB B is about to be plus some BBC local,radio )
And a PSB national mux being other BBC s4c Alba and BBC uk radio maybe uktv
And PSB UK. Wide mux with the daughter channels on.
That is just over 200 coders compared to the about 450 we have .

But there are many commercial issues etc etc so there was a lot to be solved !

Maintaining  a legacy service for anything longer than a few weeks
Like we did at DSO is not a good way forward ….
