Given I saved *just* the movie for this project, the MGM logo in my given case was ommitted. In the new R1 bluray file structure, the MGM open is its own entity. But once I edited that section out of the mono wav file ..again for my given way I needed / used it.. the results were PERFECT! The wav audio offers a lossless presentation of the original mix, and I am still able to sample the new 5.1 remix with a touch of a button. It is amazing how many changes were done, and by keeping both mixes, it is very easy to switch back and fourth.

And I will begrudgingly admit to this as well: While the original mono mix should have and *always* needs to be included, being able to switch back and fourth did bring me a little more appreciation for the new very aggressive 5.1 remix. Not a complete appreciation, as I still prefer the original sound effects and opening music cues, but having both options really makes a difference.
