Digital left and right with a monaural soundtrack

let me think..............................................?
You could route the DME mix to the centre channel only but that can only be done with re-wiring the outputs from the AVR as the AVR THX is not that cleaver in thinking? So you un-wire the dialouge music and effects from one of the L/R fronts and wire it to the centre channel (and this is only for a first run for friends).
Next you wire the M isolated music only track and undo the wires from the surrounds and wire them onto one of he fronts that is outputting the music track and bingo you have a strange like duel mono of the music playing from centre when it cuts in..along with the surrounds.
Yeah I never thought of doing something like that before, but then again I don't have Laserdisc with special features such as Live and Let Die?

Digital right is the musical score only. Digital left is the complete soundtrack (dialogue, effects & score). If you were feeding them both to your receiver, then you would indeed end up with a very odd 7.1 mix.
With the above and I would like a set-up like that.

I'd do it with a few RCA Y leads one attached to music only Right output so that lead feeds audio to all surrounds equally.
Unplug Left output and the centre channel and connect centre to Left front and all the feeds from the AVR will be sync with my Dolby CP500's.

If you wanted to try isolated scores on some DVD or bluray I can't think of any other easier way around it expect you'd have to have two players and two AVR and two of the same titles on disc and a dozen or so more loudspeakers of the same type.
Syncing the discs up will be a bit tricky as both players of same make would have to start the film at the same time! One playing the soundtrack the other playing the isolated 5.1 score.
You could EQ or trim the highs down on the isolated score as you don't want to end up with masking issues of some middle to highs washing out the sound effects or some dialouge. But the bass range that is often been reduced in favour of some sound effects can be tightened up for bombastic listening fun experience.
The two of the same AVR is not curial just as long as the signal has been decoded that;s all that matters.
Having a master fader to control all (unless you like to use two of the same AVR) as the remote can then control at the same time. Otherwise you'd need a 12 or more channel fader to with lot of inputs/outputs and one master fader for them all, to lower or raise the volume.
