If I configure a DM8000's tuners as follows (you do not need an actual rotor to test this, just pretend it's there):
A = Rotor
B = linked to A
C = Second cable from rotor A
No matter what i do, tuner B will never be used. This configuration should allow me to record from 3 transponders simultaneously, but Enigma2 only allows me to use 2 tuners. For example, when two recordings are running it shows A and C in use, but it only allows me to use those two transponders.
A workaround is to LIE to Enigma2 and claim that C is just a dish pointing at 19E for example. In that case, I can use all three tuners as expected, but this will lead to failed recordings when the rotor turns away from 19E.
It's a bug, because E2 allows me to set this configuration, but it does not work. Obviously, I hope that it can be fixed by making it work rather than just forbidding the configuration...
