That can certainly be arranged. I have both on my drive(s) somewhere. Once I dig them up, I can send them over.
You don’t need an actual, physical surround sound speaker setup to do the comparing and contrasting. Media Player Classic and the a/v ffdshow filters run on Windows. If you’re running that operating system and have that software installed, you can load up the 1994/2003 audio tracks in separate player windows then do the channel soloing stuff from your computer while wearing headphones. But if you’re willing to take my word for it, then none of this is really necessary. The 2003 DVD audio (the one that’s NOT the “Enhanced Home Theater Mix”) is the original mix. Save for one minor hiccup, or burp in this case: if memory serves, the belch that Simba lets out in the “under the stars” scene after Hakuna Matata has reverb thrown into the front channels to sweeten the effect. In the LaserDisc/theatrical mix, it’s completely dry— no reverb in the fronts. You’ll have to patch that once you have the files.
