During commissioning (after device) he wanted to install a firmware update, but that did not work over Wi-Fi, it always and constantly came the error message that it is failed and that I should check my network connection, etc., but it was always present , Power on / off, reboot, disconnect it from the electricity etc. all in vain, nothing went.
Then click on the Sony website to the data to the machine and the option "Software and Download" and then click the button to the firmware download, to try it on a USB stick.
The great thing was that on the opening page then no firmware was available for download, just a text description on how to make the update with the recommendation that at best do on the Internet. Toll.
Then have to look elsewhere, the firmware found (not Sony, who apparently did not himself) and installed on a USB stick, then was first peace and the constant information about an available update SW no longer came.
Thus, movies flawlessly for DVD and Blueray. The Amazon Prime app takes forever to start, quality when streaming rather poor, although there was an HD movie, reminded me somehow of my Sony TV, there it also takes forever, but the image quality when streaming is true at least in TV.
Running noise I have not heard so far, but I do also like movies with a certain background noise, where such a thing is not well noticed.
So all in all, to compensate for a useful device, but for commissioning Needless strong nerves and the possibility of the lack of support / download link sent by Sony.
