That's interesting, I thought hairy hen had used primarily the Definitive Collection laserdisk with some of the 1997 SE laserdisk for the latest version (version 2.0, I guess) of his Star Wars 70mm theatrical soundtrack reconstruction/restoration. Has he switched to an even better more accurate source for his restoration?

I assume when you say DTS-HD MA 5.1 soundtrack you are referring to the Star Wars 70mm reconstruction, since I think that's the only such soundtrack on the V1 Star Wars Blu-ray. But maybe there's more than one DTS-HD MA 5.1 soundtrack on the V2 Star Wars Blu-ray.
