Ok, that seems to work well.I have rebooted a few times and can tune live  
tv now.
Thanks for doing the tests on those mods.I had to call the file in  
mythtv-backend.service.d mythtv_backend_override.conf as I could not save  
the file with dashes in the file name.

I will add the HDHR tuners now and see if they still have problems.
Then look to see why my xmltv script isn't populating the guide.I am  
getting
"Unknown xmltv channel identifier: tv2-plus1.freeviewnz.tv - Skipping  
channel." for all channels but it was working before.

Cheers
