You don't need advanced, with your set up, unless you are also using a Diseqc switch and have both the fixed, and motorized, LNB's connected to both tuners.
If Tuner A has the motorized dish set Tuner A to Simple, mode to positioner and enter your latitude, and longitude.
If Tuner B has the fixed dish, on Astra 2, 28.2E, leave that as simple, fixed dish, Astra 28.2E.
If the moving dish icon is flashing, and never reaching the selected satellite, then you need to check if the motor is actually moving your dish. Try changing Tuner B to Not Configured, set Tuner A as above and see if the dish moves to the satellite.
You can also change the preferred tuner, go into Menu, System, Customise, change the top heading to Expert and scoll to Preffered Tuner and try it on A, and then B, to see if that helps.
If none of this works please post more details, regarding your motor, and how it's set up.
