Sounds interesting there 8t88 ;)
I got a PM on another site with the following about the Alien Laser disc mono track:
This disc has only mono surround on the Dolby Digital track. The picture and the Dolby Digital soundtrack was mastered from the 70 mm release version. The soundtrack contains therefore some alternate dialogue, rough sound editing, different/enhanced sound effects, and is missing some dialogue which was contained on the Dolby Stereo sound mix of the 35 mm version.
I've not watched the Alien Laserdisc since 1994 (i think) Does anyone know if this is accurate? Does anyone have the mono track from the Alien laserdisc at all?
