Ok, now DMM has fix for freezing issue on Hd channels. But I already sent my unit to them. I wrote letter to support September, 9 that I will send my 800, but they do not notify me about upcoming update. Now DMM will return my unit with upgraded OS (I can do it myself) or they repair hardware?

Hi! I have problem with such configuration: DM 800, Stab HH90 and diseqc 1х4. On motor i have 2 LNB Linear and Circular. Problem is I can't setup diseqc switching. Lnb switchin sometimes one to another, but not switching back.
PLease, describe how I can setup this system right.
