I have NO Problems at all running my Elite here in the 1.2 mode.
the Elite has been running a 10-fter on a H-mount for little over a year now an has work flawless for me. the problem for most people most likely is a corrupt channel list, an they may not even no that is the problen. A wile back when I up-graded firm-ware (3880 & 4295) it changed some of my position #'s around, an I used MAZ 2.3 (channel editor for the AZbox) to find that problem and correct it, an it has worked great ever since. it took a few days before I found what was causing it, an some trail an error but got it, an it came down to 2-satellites that I added to it's list.
the AZ does have have a nice 1.2 motor control function, as far as bumping the dish east or west, you can select different modes of movement 1-2-3-4 contious, far better than Pansat receivers.
if you're looking for a receiver that is bug free Skyscanner good luck all HD receiver that I have use have some kind of bug, or certain things that they will not do as well as another model. now as far as the AZ it is 1 great receiver, an has great potential too, along with 1 of the best I have ran. but you need to under stand it is a linux based receiver, an once you understand the basics you will be good to go.
