Just about the time DVDs were the new best thing, I bought a sealed laserdisc copy of a double feature of SILENT RUNNING and COLOSSUS: THE FORBIN PROJECT, both in widescreen format. I debated for a long time about whether to open it and watch COLOSSUS, or sell the sealed copy on eBay... I did sell it still sealed, (many years ago), and got enough from it to buy about a dozen and a half other laserdisc movies.
I have tried to figure out if it would be reasonable to make a laserdisc to DVD transfer (somehow), and decided there are more than a few 'challenges' involved. For instance in NTSC format, VHS tapes have 320(?) lines of horizontal scans, laserdiscs have 425 lines and DVDs (nominally) have 500 lines, (BluRay has 1080 lines in I or P format). You can see the advantage of the better laserdisc resolution as the largest part of the improvement to DVD capability.
However, laserdisc is recorded with (digitized) analog information, and from having used the pause/frame advance features, it seems that the laseridsc uses the picture interlacing to create more color shades than would be possible if each frame contained a "steady" color like DVDs appear to use. For example, one interlace might have a purple pixel, and the other interlace may have a grey pixel. The cathode ray TV picture tube, and the viewer's eyes will 'average' the two pixels into a viewed color shade that might not be possible any other way. This technique would give the viewed movie a much smoother appearance than what the early DVDs did. Since then, a lot of digital manipulation is done on the raw DVD digital data to even simulate motion blurring that was a naturally occurring feature of the analog TV and film cameras. I believe there is also the difference in resolution of the colors with laserdisc having 8-bits, and DVDs having 10-bits, (depends on the players used though).
And then you get into the legal/copyright issues. Is the copyright current, and then who owns it? What about the soundtrack music copyrights? What countries are the contracts for the copyrights valid in? The DVD of VALLEY GIRL was held up for years trying to sort out the music rights...
And speaking of soundtracks, laserdiscs have at least six different formats.
Besides the obvious mono (one track only), and stereo, there are the different formats of stereo - L/R, CX, Surround, Dolby, AC-3, DTS, and then there are variations of those where there are also isolated music/comentary tracks that the players can select as well. YIKES!
How have the DVDs been created? Many, if not most, of the DVDs of older movies have been created from film copies used as originals and digitized. It is much simpler to go this way.
The whole problem with this approach is whether there is a film copy available, and if it is a 'decent quality' copy or even an original 'master copy'. It is easy to tell which ones were done this way (cheaply) because you can see film artifacts (color shifts/variations, dust, spots, or fiber strands) in the picture, or the occasional yellow circles in the upper right of the picture (these were a cue to the film projectionist to prepare for, and do a reel change).
I hate to say that there are VHS to DVD transfers "out there". Unless you are desperate to view a particular movie, you probably will not be happy with those. (No, I will not name any of the ones I know about.)
Bottom line is that even though there are laserdisc widescreen versions of COLOSSUS in the world, it would be expensive to create a DVD format version. The commercial prospects of recovering the investment from a limited (read that as 'small') audience seem unlikely, nevermind earning a profit for your trouble.
But, I sure would like to see a widescreen version of COLLOSUS...
