Thanks GregK! Jurassic Park is my favorite film. Having owned many different versions of it on video, I've become very familiar with the mix. When I first heard the 7.1, I knew it was wrong. Not bad, just wrong.
Thanks again to everyone who helped me and all of us realize this dream. I'm curious to see if Universal uses the original 5.1 or a remix for the upcoming 3D re-release. One thing is for sure: the trailer's 2D image looks to have improved vastly over the Blu-ray video master. With any luck, we'll get a nice, new Blu-ray as well!
Looking forward to 20 years of Jurassic Park! Life will find a way...
