I use DiSEqC 1.1 in my second tuner configuration. (DM One)
In original Dreambox images, There is an option under "tuner conguration" called "committed DiSEqC command" which help me to configure ports like: AA,AB,BA,BB.
But I cannot find it in your image. Obviously, There are "input 1,2,3..." option under DiSEqC 1.1 but when I test it, It does not recognize the satellites via these options.
Pleasse kindly help.
