Last week I received my Oppo BD-83 which I have connected directly via HDMI to my LG television and via digital coax and analog cable to my 1070. In going through the setup of the BD player, one option is the LPCM Rate limit. The default is 48K with options of 96K and 192K. I couldn't find a reference to the rate in the 1070 owners manual (although I may have missed it). What do you suggest?
