Which are the correct Vu+Duo tuner configuration settings in Menu/Setup/Service searching/Tuner configuration which allow me to run a MOTORISED DISH on Tuner A and a SINGLE SATELLITE DISH on Tuner B ? Ive got configuration mode 'Advanced' selected on Tuner A for the motorised dish, that seems to be okay. How do I set Tuner B - 'simple', 'loopthrough to' 'equal to' 'advanced' - i'm not clear on this.
