I have received alot of help from various members on here and really appreciate it. Hopefully this can make it a little easier for others.
Just to give a quick start to anyone searching.
Here is my current setup...
OpenMediaVault Server with Docker Containers
Rpi Channels Server
WayPonDEV Link Pi ENC5-V2
ADBTuner Docker
Onn 4K Google Tv (Using Wifi, ADB Debugging On, HDMI out plugged into Link Pi)
FireTV 4K Max on TV's for viewing Channels DVR
As stated in other threads I had to change the streaming endpoint to http://192.168.1.41:8090/stream0 in ADBTuner so it would stop continuously restarting the streams.
Also the Video Mix under the Extend tab can be a little finicky. Be careful not to accidently re-save default layouts in Layout Manager or it will change the names to Chinese in the current firmware (2.9.0 build 20231229_1901).
Setting the framerate to -1 in Encode can make the Mix Channel/Output Blank or unviewable in current firmware (2.9.0 build 20231229_1901).
