I have not seen any model Viewsat that has good motor control.
I guess motor control is not a priorty at Viewsat.
Did it work with earlier firmware version? What version did your rec come loaded with? I have some of the previous files on my hard drive, I could email you if you want to try. They've been really slow about updating the firmware for the Ultra. I don't use a 2100 type motor to move my dish, so that part of their firmware hasn't bothered me. Getting the AC-3 sound to work has been my biggest gripe with the factory firmware lol.
