I have a new Duo4K in which I installed latest satellite tuner (45308X chipset) and terrestrial one. In Tuner Configuration menu I see 10 tuners, maybe due to FBC feature. 8 satellite tuners, 2 terrestrial. Sat tuner has 2 RF input ports and terrestrial has 1 port. I connected my 2 dishes with universal LNBs to both sat tuner ports (the first dish to port A, the second one to port B). I have no advanced configuration like diseqc, SCR or similar. So, which tuner is connected to physical input connector A and which to connector B? I think that I can not use other virtual tuners with my configuration. Also, the same for terrestrial tuner. Which one is connected to the unique input connector? Could you please clarify this feature? I'm using Blackhole 3.0.9b image. Thank you.
