That did it.

Unfortunately that killed live TV for a bit but it is back now albeit with the default timeouts extended.

I cannot express my gratitude for your help sufficiently.

Than you.

Great that MythTV is now working for you.

From my experience, the default timeouts for DVB-T/T2 for UK Freeview Capture Cards of 1000 and 3000 need to be increased to 7000 and 10000 respectively. This works most of the time, but there is an issue with Live TV in that it does not always work or channel switching times are long, this does not affect scheduled recording of programs. I have raised a bug report on this (it is a bit technical), but here is the MythTV trac report reference https://code.mythtv.org/trac/ticket/13292

I spoke too soon. After rebooting and a system update. I had to re-compile the TV-Card drivers.
dmesg confirmed it/they were in place.

The backend was restarted and the frontend appeared to do nothing.
Restarted from a terminal, it could not find the database.
Both are on the same machine.
The terminal history is:
