Supposedly, h_h got access to Pro DPL decoder software for the latest DeEd’s. So ROTJ 2.5 may sound better (or not).
Correct. The most recent 5.1 versions for all three films were created using official Dolby software, so they will sound quite close to what comes out of a Prologic II equipped receiver, aside from the minor modifications I made for the handling of low frequency content.
Actually, I’ve given some thought to using the original Prologic for a possible new version, since the surrounds would then be more fully mono, and front-channel crosstalk greatly reduced. This may not be an improvement to everyone’s ears, but it would be a rather more authentic presentation. I’ve done some tests and I like the way it sounds for these movies quite a lot. Combine that with a new approach to the LFE track and it could turn out very well indeed . . . assuming, of course, that I have the time to do it. With a Disney release of the original versions not looking likely any time soon, my motivation to revisit them seems to once again be on the rise (based as much on my annoyance with them as a company as anything).
