It is a 29.97 interlaced master tape not 24 fps film.
They then had some intern pretend to inverse telecine it back to progressive for the DVD leaving all sorts of interlacing artifacts.
As a result you are left with damage that cannot be repaired without orders of magnitude more difficulty.
The laserdisc, still telecined, can be cleanly IVTC'd properly to restore the original frames.
The artifacts also increase the complexity of the video, burn bitrate, increase compression artifacts, and prevent reasonable upscaling to anamorphic.
