The 6500 has a good menu, a great image (what I expect from a BR player) and is quiet. So I do not know if all of those who write the 6500 was too loud, bekommem poor box have (serial dispersion), or whether they have mouse ears.
When reading the disc you can hear what, that's normal, but after that it's pretty quiet. So my wife and I have heard even in quiet passages nothing. Since the LG was much louder, which had a permanent buzzing sound, the one still heard even at low volume.
Yesterday I tried out various formats via USB. Everything went without problems, AVI. MPEG and even MKV which indeed come more and more. The MKVs I could even coils at full speed, because the LG has remained basically hang out and caught the film from the beginning, which is of course ägerlich if you hit the wrong key or even the film does not want to see finished, then the wars at LG , No chance to eg 88 minute coils, by not possible time entry.
I did not test music, but I have other devices.
I can fully recommend the 6500.
