Problems getting my sat to move my motor

I have just bought a silvercrest system fron Lidl an a Stabb hh90 motor from Maplins. The system says it drives Disq 1.2 but certain satellites eg Astra 19 and hotbird have no provision in the setting.
I have tried the manual scan but all the other channels go.
I can manually set the dish to gat astra 19 but then it doesnt move when i go to another satellite.
Please help before i lose my mind.
