A very big disappointment!

Since 2009 I use my "old" Technisat HD S2 Plus. When I saw the new possibilities opened the ISI S1, I ordered it immediately and looked forward huge it. The unit was delivered quickly and I have made myself with anticipation to the device.

And then it was over with the joy. Image quality was good overall though, but compared with my 5 year old HS S2 Plus much worse. In particular, sharpness and contrast have disappointed me. Also adjustments to the projector did not help. I operate the device with a high-end projector on a 3.50 meter-wide screen because Distinguish fall on very strong. I was so surprised by the difference that I showed my wife on both devices movies. They also found the HD images of S2 Plus better SD pictures even quite significantly.

On top of that the ISIOzeitweise glitches and had ISIPO not working. The unit returns to the sender.
