Automated color correction using reference frames?
Time

I have an Excel spreadsheet that might be of use to you.

Basically, you pick a few pixels from source (A) and enter the "observed" YUV values into the spreadsheet. You then take the YUV values for the same areas from source (B) and enter the "target" YUV values - what the colours should be. You then adjust various parameters (using Excel's Solver if you wish) to get the observed and target as close as possible.

These parameters can then be exported to a ColorYUV command in AviSynth.

The procedure works best with test cards which have large areas of solid colour. A complex picture may be harder to match.

Preserving DTS LaserDisc tracks, specifically Jurassic Park
Time

This plugin for winamp is ancient, and never got updated when DTS started encrypting their CD-ROMs after about 04-05, so only films prior to that with DTS tracks could be utilized. 

The plugin you used: is it called APT-X100 DTS Decoder? I remember finding this the last time the '97 SE discs appeared on eBay, but as the seller was asking silly money for the discs I didn't pursue ripping methods at the time.

You are correct that the encryption that was introduced c. 2004 was never cracked, and later discs are still unrippable.

Well done for this. I can't think of a better example of a theatrical DTS soundtrack - I still remember seeing that "Digital Experience" bumper in the cinema, too!

BBC2's 27th May to 2nd June 1995 Forbidden Weekend (Released)
Time

Not horror-related, but this reminded me that the first time I saw Monty Python's Life of Brian was during Channel 4's 1991 Banned Season. I found a discussion and a list of what was shown in that season over on this forum here.

I also remember watching the documentary "Sex in Our Time" that followed the same night; what initially sounded promising ended up being just a group of women sat around talking about their vaginas. I also seem to recall that any interesting parts were broadcast as audio only with the video blacked out. :-(
