This wav plays back through proper "channels" using other software players (e.g. Nero, Creative MediaPlayer etc.)
MC settings: down-mix mode 7.1 (so there is no downmixing) all speakers at LARGE; all trims at zero;
When I playback the file (USB), many of the channels (as measured on the MC analog outputs with scope) are not correct.
I checked and 5.1 wav PCM is fine wrt correct channels being used.
I will send my sample 7.1 wav file to OPPO.

Just to be clear, the above issue with 7.1 is ONLY for media file playback. I checked using the AIX Audio Calib. Blu-ray disc using 7.1 24/96 LPCM and the BDP-95 MC channel mapping is correct for Blu-ray decoded audio.
There is a 7.1 24bit/48kHz PCM wav file from Microsoft for testing purposes (with sequential voice-over in each channel) available via this page (the 8 Channels Test File link near the bottom) . Also includes the corresponding wma pro MC file.
This 7.1 wav file has this voice annotation (clockwise channel voicing):
" Front-Left, Center, Front-Right, Side-Right, Back-Right, Back-Left, Side-Left, SubWoofer "
Here is a multichannel timeline view of this file (using Nero 7 WaveEditor). The channel designation is shown at the left. The vertical order of the channels as displayed is the actual packing order of samples in the wav file. The "BL/BR" (back left/right) shown corresponds to the Surround Left/Right channels of home theatre players/receivers while the SL/SR (Side Left/Right) correspond to SBL/SBR in home-theatre designation.
