dish not moving with vbox untill i go into tuner config every time

hi all
using 203 image on vu+ duo
i have everything set up for diseq 1.2 using a vbox, each position stored with a different number, all working perfect on dreambox 800se
with the vu i have to go into menu/set up/sevice searching/tuner config/tuner a/then go down to satellite and change that to the sat i want to go to and then press ok for it to move.
as i said i have all satellites set up but it will not go to another satellite automatically on a simple channel change as it does with dream
cheers guys
