Unfortunately, far too loud fan in the player and Verzöerungen in tone compared to the TV picture

What did not work, is the volume of the fan in the player. Produces a sound unmistakable that interferes extremely and again particularly noticeable when the fan off or starts.
In a system such should have the fan noise better control. The system should provide a reasonable surround sound, unfortunately it provides an additional, tinny buzz Rauschmix by the fans and that's very disturbing.
There's a lot quieter fan and it is absolutely incomprehensible why the noise is not noticeable in a final inspection.

A second point is a delay in the sound compared to the TV picture (a Panasonic TV to use VIERA Link).
This delay accumulates even over time. The sound delay can indeed be on the device to 0 ms set, but that does not help. Here it makes no difference whether one übertträgt data optically or via HDMI from the TV to the player. That irritates and you hear a starting signal only when the athlete running already.

Too Bad.
