Previously I had a Bose solo and after they had 2x a non erkärbaren error followed the tip of a recession of Bose solo experience and the BDS 330 fetched. Actually, I'm enthusiastic about technology, what solo for the first time led me in the Bose astray. She was just, sound and power plug in and good sound. Compared to the BDS 330, however, the Bose is a very broad piece away. Especially when the subwoofer Harman Kardon has a very strong sound. But what is not like the fact that the lip-synching does not fit. This is perhaps most looping through the HDMI through the BDS. Is it possible to adjust but sometimes, when you switch the BDS gets wrong with. If I then go into the setting LipSync and without changing out again, it fits again. Meanwhile, I have put on 240 (max) and the BDS receiver from the LipSync 100. After today's update of the software, it seems to be better. As I said sometimes the system no longer remembers the Einstllungen and then it's highly visible, that the sound behind the picture is lagging behind. Therefore, the point deduction, hope with the firmware update is now corrected. Note: my TV (Phillipps 47PLF) has no return channel function via HDMI. Could the reason for the problem to be.
