IIRC, VOY and DS9 were stored for long term on videotape, with the original footage deleted from the disks, while TOS and TNG were still (kept on) reels. Remastering film is a lot easier than upscaling low quality videotape, especially since that is also vulnerable to EM and much more to heat than modern film. I think the Laserdiscs were created from the original footage, so you have some proper gold here. You might be able to create even better upscaling with this than CaptRobau: …blogspot.com/…/how-did-i-upscale-star-trek-ds9-f…
