Openatv 7.5.1 - problems when using serviceapp/exteplayer3

[BadBlake1]

Where can I get support for openatv 7.5.1?
I have encountered problems when using serviceapp/exteplayer3. When using it, I cannot view channels downloaded from my server using remote channel stream converter or fallback receiver. This is not a problem in openatv 7.4, but in 7.5.1, it does not work.
Hope this gets fixed soon as I'm still on openatv 7.4 -no sense in upgrading now
My setup:
Vu+ Uno4kse -server connected to sat dish
Vu+ Duo 2 -client -receives channels from server using Remote Channel Stream Converter or fallback receiver
