I have not bothered to look, but I am almost certain the advertisements are Sadoun's. These advertisements are annoying when you go to edit on some screens. If history repeats itself, there will be a file released soon that does not have these advertisements.
I have no way to measure and see if the motor controls are accurate to within .1 degree. The motor controls are very accurate and stop my 1.2 meter dish at the same place in the arc.
The motor controls are consistent and I have not had any problems with the dish motor getting "lost" or "wandering" in the arc. After running this receiver a few months, I would say the motor controls are extremely accurate and they do carry to two decimal places(.00) in this receiver, whereas most stbs carry only one decimal place(.0).
