I was going through the Laserdisc version of TLW:JP here, and having compared it both with the HDTV and Bluray versions, I found no extra image in the Laserdisc version.
Infact, the Laserdisc and the current JP2 Bluray have the same framing. Maybe the Bluray gains a bit on the left and the LD one gains a bit on the right, like so. And the difference is so microscopic that its hardly something to be bothered about. The height is the same.
I will even go as far as to say that the framing of both LD and BD are the exact same, as my eyes may have tricked me into seeing a difference which isn't there! There is no noticeable difference in framing as identifiable as with the Jurassic Park LD and BD. The HDTV version is taller than both the versions.
I haven't check'd the sound though. I'll let you folks know after I've gone through it in a detailed manner.
Video Quality: Wonderful! Great restoration!
