Maybe I don’t know enough of this, but would it be possible to install Kodi and use that and it’s plugins for satellite? Plex also had this, and maybe Jellyfin is a good option?

In that way, you can show your satellite channels but in their interface.

Maybe that can do the trick?

This is a 100% noob question, I know.

But can someone who used Lineage and Graphene say why they prefer the one they do?

I’m standing between choosing one.
