Hi, My friend moved to Kuwait and took Vu+ Zero. Unfortunately it can't get any sufficient signal to work. There is also another receiver Humax HTV-1000S that works very good with that installation on HotBird 13E. When switched to Vu+ Zero - no picture on any channel on 13E. What may be the reason - too weak satellite head? Is there any difference in images that could increase sensitivity of the head of the Zero?
