Well, it means that you can still get stereo output with the BDP-93. You will need to set the audio output to stereo (the "Downmix" setting on their earlier players), and the left and right channels will be a true stereo output while the other six channels are ignored.
Although this works to get analog stereo output via the 7.1 outs, it's not very practical. Frankly it's a PITA to do, given the downmix option is buried in the menu system.
I have an Oppo 983H + a Panasonic BD60 BDP. As you know, the 983 lacks dedicated stereo outputs. For zone two use, I have to set the audio to downmix. the problem here is the downmix is also applied to the HDMI audio, so when I want to use the 983 in my main HT, I have to go back into the menu and set it back to 5.1, which gets old real quick. my solution.... I just use the Pan BD60 for my zone two use, as it does have dedicated analog stereo outs, and I leave the 983 to 5.1 for the Main HT. Too bad I don't get to enjoy the better VP of the 983 in my Z2 LCD.
My plan was to upgrade to an Oppo BDP and remove the 983 and Pan from my rack and get down to one player. There may still be hope for the Oppo 93 given it has two HDMI outs.
Can a user have one HDMI out going to the Main HT system and set to MC sound (5.1/7.1) and then use the second HDMI out to a zone two LCD, set to 2 CH stereo ... and retain the 5.1 audio setting of the main HDMI output? In other word, can downmix be applied to individual HDMI outputs on the 93?
I find it very shortsighted that Oppo chooses to omit dedicated analog stereo outputs on the 93 given this would solve my current system needs.
