stop dish moving

Vu+ Duo2 Quad Tuner

Tuner A and B 28 fixed Dish
Tuner C and D Motorised

If I have the tuner C/D on say 19 or 13 deg and I switch to a channel on 28 how do I get the motorised dish to stay still and use tuner A/B of fixed dish.
I do not want it to move from 19 or 13 and go to 28 I want to use the fixed dish for this.
Hope you understand what I mean.

If the preferred tuner is set to auto then the box will use the fixed dishes for 28e when channel zapping.

However if you have crossepg configured to use opentv sources then it will use the motorised dish for doing an epg download.
