Yes it works fine on DVB-T too, however as Nick infered there are 3 
multiplexes so 2 tuners doesn't quite cut it.

However in reality the 3rd multiplex (Kordia) carries channels most 
people don't watch much (Maori TV, Parliament TV, FreeviewHD, ChineseTV) 
so generally 2 tuners is fine, especially if you have 2 sat tuners as well.

As far as only recording true HD on the DVB-T system, then yes that 
should be possible. You will have to have a play around the custom 
record <http://www.mythtv.org/docs/mythtv-HOWTO-12.html#ss12.5> settings 
(and have a guide with HD shows marked) but it should be do-able. There 
also is a setting specifically to do with prioritising HDTV shows, but 
it requires a flag in the DVB stream I think. Can't remember the details 
but I don't think it will help you with what you want. But try custom 
records.
