The DTS Laserdisc had the movie's LFE channel boosted, because this was standard practice for DTS at the time to make its format sound "better" than Dolby. (At the time, DTS did all encoding in-house. Nowadays, they just license the encoders and let the studios do the work themselves.)
When the first DVD was released, it had less LFE than the Laserdisc. This led to a wave of complaints that the DVD was "wrong." In response, Universal eventually reissued a "corrected" copy of the disc with the LFE boosted.
