I don't understand what you're trying to do, you mention stereo but you also want a centre channel which means it's not stereo. You also have no upmixing or downmixing selected and stereo but the input and output is 8 channel (which doesn't make an awful lot of sense to me).
do you want a stereo source upmixed to multichannel?
Im sorry I thought I explained things fine, let me try again.
I have an 11.1 setup, when I play say a youtube file that's usually 2 channel I want the dialog to come from the centre channel.
One of the experts on here said I needed to set up DPS for 2 channel and all the other settings as I have in the image shown above.
This does produce the dialog through the centre channel, Im not looking to upmix two channel material to anything more than what it is, 2 channel.
I don't want 2 channel to end up multichannel.
When I play a 7.1 channel film which is verified as 8 channels on the audio path (see image) all I get into my pre pro is 5.1 channels (see image)
I cant reproduce 7.1 channels into my prepro, only 5.1.
When I play the same 7.1 channel disc from my Oppo player, my pre pro displays the 7.1 on the front panel of my 160 as it should.
I just cant get JR to display on my pre pro 7.1 channel BDs which the audio path states as 8 channels correctly, they only ever display on the front panel as 5.1. All these images I have supplied.
I hope you can now understand what Im trying to say ?
