Yes I do use darbee , I use about 35% for 3D & Blueray , and 45% for SD.
As u probably know , it is best to adjust all other video settings from your display , VSR adjust to taste !!
It's an ok player for the price , I just wish the transport was smoother , but it is just about the best u can get now a days !,,
I, m thinking back to my first DVD player , the Pioneer Elite DV09 , of course the video quality was not as good ( bad CUE ), but great transport.
