Thanks for your response; no, I'm not confused.
I suspect that you are right about bypassing LibreELEC for something like tvheadend. I've read that LibreELEC is user friendly, and it seems to be very popular with very good support. Therefore, I thought that it would be worth exploring having LibreELEC as a guest OS from within Fedora. I believe that this approach depends on whether the "hardware passthrough" is viable i.e. having the pvr hardware accessible to the LibreELEC [virtual] guest OS. HAS ANYONE TRIED THIS?
