Do you really mean *but* ? If mythtvsetup doesn't know about it, it
can't use it. See below...

Hi: We seem to have been hereabouts several times before, and I have no
directly comparable setup, but...
I suggest that you find out the frequency of the HD mux/es from your
transmitter, from eg www.ukfree.tv/transmitters,
In mythtvsetup, go to the Channel editor > Edit transports page.
Create a new transport/s, DVB (I don't know if you'll see a DVB-T2
option) with the freq in Hz, 8 Mb BW, QAM-256
Scan those transports, making sure you're using the right tuner/adapter.
It seems that the 292e may need to be switched explicitly between its
two modes, see
https://code.mythtv.org/trac/ticket/12342
(which hasn't yet reached mainstream code, IIUC)
And see, re firmware,
http://www.gossamer-threads.com/lists/mythtv/users/584487#584487
That thread wanders around into different hardware but seems to end ok.
Cheers,
John
