BTW, I was wondering if you'd go into more detail on the AviSynth plug-ins used -- which ones or combinations w/ settings for each fix-up type ... that sort of thing.

There doesn't seem to be any independent sharpen. Because of the de-noising and upscaling, I would think sharpening would restore any crispness lost during those fix-ups, as well as from the LD source. My wondering was because I made that HSL reconstruction mentioned earlier (which injects DVD resolution) and found that mild sharpening brought the laserdisc image noticeably closer to the DVD. Of course, I'm using a dubious-quality paint program function. But there are AviSynth sharpeners that work without introducing such new, obvious artifacts. LimitedSharpen() is a well regarded one.
