Thanks @Tee77
See XBOX ONE Digital TV Tuner firmware support for OSMC?.
This is supported in newer kernels for a while.
Good news is we will have a newer kernel, bad news is that isn’t happening today.
I had a look at the Xbox Tuner and can see it uses a Panasonic MN88472. Our DVB-T2 tuner (OSMC) uses an MN88473 and I remember exhaustive backporting of code to get it working on the 3.14 and then 4.9 kernel.
I could look at it but don’t have a dongle at hand which would really be ideal for verification. So maybe the best time to retire your current TVH setup is when we launch a newer kernel where things should just work out of the box.
