After a few Einstellproblemen to the receiver now runs everything as it should. The boxes are fired properly. In volume 50 already begin slowly to shake the walls. The calibration also went without problems, but I had to return strongly to the subwoofer, as it was just too powerful. Attached is the receiver to my PC with an HDMI cable. The receiver itself a beamer with 10m HDMI is connected. Sound and images come without any problems. 3D Blu Rays are sent error free. For me, my first receiver and I'm thrilled.
