Hey Abu,
not sure if you understood all of the german above correctly, so I'll try my best in english to answer your questions.
I have two FBC cards in the Ultimo4k, only one card is connected with one Sat cable, since I don't need any more tuners.
From what I understood reading the Wiki and Forums, the PLI settings differ from the ones of VTI that I was used to. Correct me if I am wrong ...
Tuner A - First physical FBC Card/Tuner
Tuner B - Second physical FBC Card/Tuner (As mentioned above, not connected, that's why I don't have it configured)
Tuner C-H (virtual "Leaf" Tuners of my first FBC card ... correct?)
I'll attach the tuner config from settings below ...
Regarding your SCR question, yes I am pretty sure that no SCR / Channel is in double use. I just double checked this again. It's the same SCR Config that I used before on the VTI Image without any problems. As mentioned in my original post, that the Sat Signal seems to suddenly vanish, while watching a channel (not when switching a channel) for no reason on all tuners, physical and virtual. Signal Finder e.g. also shows no signal on any of the configured tuners when this happens. Only thing that helps as of now is to reboot the box.
Also, described in my original post .. the lnb seems to work fine, since my also attached integrated TV Tuner in my LG Oled keeps working just fine when my Sat Signal dies on the Ultimo 4k with OpenPLI.
