The lack of clipped white levels and different cropping seems to indicate that this LD certainly did not come from the 1993 DC/Faces/GOUT telecine.
Could this be the true 'shrink fixed' version davisdvd was talking about, but released in 1993 instead of 1992?
The 1989 laserdisc was quietly reissued with the newly corrected letterboxed transfer, completely doing away with the "incredible shrinking ratio" problem.
