Hmm, I didn't know there would be issues with DTS in mono . . . but yeah, it sounds like it's probably an issue with the equipment being used to play it, not the file itself.

By the way, the DTS is not an encode of the same mono mix file that's been out there for the past few years.  In addition to splicing in the film version of the Fox fanfare to match the other mixes (the existing track took it from the soundtrack CD, but I figured this would be more authentic), it has been reduced in level by 3.2 dB so that the dialogue throughout the movie is at approximately the same level as it is in the 70mm version.  To properly calculate a digital gain change involves expanding the word length to 24 or even 32-bit precision, so I dithered the result in order to maintain quality in rendering a new 16-bit file.  So if you analyzed it in comparison to the original, it certainly wouldn't be bit-identical.

Previously I had tried to make a level-matched mono file, but the software I was using to play it back didn't do mono at the correct volume in relation to stereo, so it ended up being too low.  This time, doing it in Pro Tools, I'm quite certain of its accuracy.  The stereo mix was reduced by 2.9 dB, and the '85 by 5.7 dB (this one was really loud in the source file).  Now the dialogue is pretty much the same in all tracks and the only level differences between them are due to their relative dynamic ranges (made by mixing choices and/or format limitations), and not the average level.  So I think for the first time a truly accurate comparison of all the mixes can now be made.

I'm uploading all my new wavs for everyone, but it isn't finished yet.  I'm also thinking of doing AC3 at a couple different bitrates for possible DVD and AVCHD versions.  In the meantime if anyone is impatient and wants to encode AC3 from the existing mono file, use a DialNorm setting of -28 or it will be too loud relative to everything else.
