So the only laserdisc to contain the original audio would be the Encore UK
release?
(Here: http://www.lddb.com/laserdisc/18853 )
Also, I *think* that the original soundtrack was only Dolby Stereo
(surround) - from information at IMDb (which I know is unreliable) and some
archived posts in this newsgroup. So the 5.1 DTS and AC3 tracks on the 2006
SE DVD are likely to have been remastered at some point? (Not that there's
anything wrong with that, but I prefer to listen to a soundmix as close as
possible to the original.)
