Tvheadend

I have been pulling my hair out for some time and cannot find a solution.

I live in Australia and have a media PC which is Ubuntu. Everything runs through docker containers.

I have Tvheadend installed in docker (linuxserver, latest version).

I am using an xbox one tuner to pull DVB-T channels.

Since I was having issues with the inbuilt muxers (only one would work), I built my own.

I have created five networks for the main TV channels which each have their own corresponding Muxer.

Of those give networks, three work brilliantly and two I cannot get to work.

When I scan, they just fail.

I have checked the values in the muxer and have checked the frequencies of the channels on my actual tv with the same values.

This is one Channel (Seven Network), the other is ABC.

I am at a loss. I am not sure what else I can do. All other networks/muxers work great, it's just two of these that won't work.

Anyone have any suggestions?

Cheers!
