I have the same problem in that my motor will go to 1 destination west 30' but no others west and east it will goto 28.2 but I get no service come up no channels it will goto 23.5' but limited channels but wont goto any from 0 up to 23' the moto just dont move at all. I assume it isn't the motor becouse it will go to the end of east and west. I am using the Gemini image and have tried several scripts and quite a few satellite.xml's but still dish don't move. It's just that the sat's I want are the one's it wont goto. If some one can stear me in the right direction that would be cool.
Have you tried turning off the goto x option and putting the sat locations manually instead. As it had this problem where my dish would'nt move at all then I did this and it worked mostlly. Also if you want to use the goto x option have you typed in your area settings. got here for that
