We bought the receiver because our old and a TechniSat was and we were thus almost always satisfied. After a short time, however, it turned out that the receiver massive problems with all HD channels has. On those same channels it comes after a short time to block noise and sound interruptions lead to total loss of picture. When troubleshooting we first thought the reason would be the satellite system, so again realigned but to no avail. Bought a new multi-switch and update the firmware of the receiver also brought no success. Now that I've replaced the receiver against a Atemio AM 510 HD TitanNit also run the HD channels without problems. An inquiry at the Technisat customer service gave it there "of course" no information about gave the receiver makes trouble. However, a search in various forums showed a different picture. So a star for the receiver because he completely unsuitable as a HD receiver, however, the rest copes confidently. Five stars I would give the completely umklomplizierte Returning the Device from Amazon that I believe as the only know of the problem.
