setting up motorized dish with usals or disque help

hi guys i have put in my vu+ duo box and when connected to fixed *** dish its fine but as soon as i put it on my motorized dish with the long and lat it goes about 4in to far east.

i have tried the disque 1.2 but im not sure how that works it was simple on my sider to manually tune the sats but not with this vu its doing my head in. please help as when i connect my older spider box to my motorized dish it picks up all sats fine and i can watch the lot any sat

here is my long and lat.
can you tell me what i should put where maybe im doing it wrong
thanks

any help welcome.
Latitude = 51.8557, Longitude = 0.5231
Lat = 51 degrees, 51.3 minutes North
Long = 0 degrees, 31.4 minutes East
If you want to point a satellite TV dish at Satellite= 13 East orbit longitude
Beam elevation= 29.6, Azimuth= 166.4 (magnetic compass), Polarisation= -9.6

please guys im getting so frustrated its fine when connected to my fixed *** dish i loaded image lines boquets but as soon as i put on my mororized it wont pick up anything.
