Congrats.
Odd that the Laserdisc didn’t have a Dolby track.
The US laserdisc seems to have had a Dolby Digital 5.1 track, though the JP laserdisc was stereo only. Without having access to the laserdisc 5.1 audio, I would guess it’s essentially the same as found on the later DVD (released in 1998).
DTS and Dolby Digital were relatively new and competing formats in the mid-90s, and they handled surround sound mixing differently. I can only imagine that the issues with the 5.1 mixes used in home releases were a result of having to remix the DTS soundtrack into Dolby format (assuming it wasn’t actually a ‘fake 5.1’ upmix from stereo).
