Thanks. That looks like roughly how I suspected it would work.

Unfortunately, I don't currently have any (practical) way of testing
DVB-T at the moment due to poor signal strength and a lack of a cable
between the loft aerial and anywhere.

It won't be easy. Apparently, there's currently no way of sharing
state between the analog portion of the driver and the digital one
using the hybrid approach. (It looks like a separate instance of the
driver is used for each, and communication with the analog one seems
to be severely limited by the API.)
