Wow, that's a lot of DTS titles you own!I'd love to have a few more personally, but it's primarily Goldeneye and Tomorrow Never Dies I'm after.
Theatrical mixes seemingly and not reissued If I am not mistaken:
013) … Casino (1995) 43117: The BD is DTS 5.1 but likely a new mix. I have the regular LD and love the sound.
019) … Dark City (1998) ID4643LI-theatrical was reissued as a bonus to the Director's cut and not in DTS.
022) … Die Hard (1988) *** 0890584-original sound mix altered for all 5.1 remixes.
023) … Die Hard 2: Die Harder (1990) *** 0890684-need to check but may be same as first film.
024) … Die Hard 3: With A Vengeance (1995) 0885884-New BD audio very strong but not as detailed as a 1995 film should be, suspect a remix and not theatrical.
046) … Hercules (1997) 15067 AS
048) … Hunchback of Notre Dame, The (1996) 12354 AS
075) … Pocahontas (1995) 12158 AS
These Disney films all get 7.1 remixes nowadays, so these are original.
053) … Jackie Brown (1997) 15065 AS-BD mix is DTS 5.1 but may be sweetened as Tarantino likes to tweak his films for video.
054) … Jackie Chan's First Strike (1996) ID4713LI-AMerican dubbed and re-cut version.
082) … Ronin: Special Edition (1998) ML107602-BD uses LD DTS bitrate so it may be the same track. Someone with both will have to compare side by side.
088) … Shadow, The (1994) 43116-I have this one and the sound is STELLAR. The German BD has LD DTS bitrate so it may be the same and theatrical. Again someone with both would have to compare.
039) … Goldeneye: Special Edition (1995) ML105987
102) … Tomorrow Never Dies (1997) ML107148 Both of the Bonds, lose heavily in the remixes. Goldeneye loses it's thunderous bass and LFE, and TND loses the surround clarity and in it's unbelievable discrete effects. The 5.1 ac3 versions and SE DVDs are okay so it's only on the 2006/BD remix.
105) … Vertigo (1958) *** 43212, is the bad 5.1 remix with horridly intrusive new foley work. The new BD mix is supposedly a new and more faithful mix. The film is best in original mono.
As far as others, here are a few off the top of my head:
The "Director's Cut"s of Lethal Weapon 1-3 are DVD only and have full bitrate DTS.
Die Another Day has it's original DTS-ES matrixed 6.1 channel mix on the initial SE DVD, and on no other version. The World is Not Enough had a similar mix that was never released. The Japan LD is theatrical ac3 Dolby EX matrix 6.1.
DTS audio for Batman Forever never released. All mixes on 2005 DVDs and BDs for the original Batman series came from heavily filtered audio masters and then put into Dolby/DTS codecs. LD has theatrical audio in ac3 and Dolby surround.
Original DTS for The Matrix never released.
