The only thing I had to do to get the T292 working was to upgrade to MythTV 0.28 as the driver for the T292 requires the application to understand how to switch between DVBT & DVBT2, the T290 driver doesn’t (didn’t, I think it’s changed in recent kernels).

Autoswitching between DVB-T and DVB-T2 (and between DVB-S and DVB-S2)
in the drivers is not the way it is supposed to work.  It was added in
some early drivers because so much software at the time simply did not
have the switching capability.  Now that the software can do it, the
drivers are not being written that way any more.  As of MythTV 0.28,
it is supposed to be able to do the switching, but I have never tried
it myself.
