Was able to get a capture of that color bar signal, and calibrated it by using the excellent method Moth3r came up with here: http://originaltrilogy.com/forum/topic.cfm/Moth3rs-guide-to-LD-capture-colour-correction-using-AviSynth-emphasis-on-correction/topic/14582/

So here's a sample of the beginning of side 2 again, calibrated: http://www.sendspace.com/file/a0spf9 just so you can see for yourself what it looks like and what I'm working with.

I have since fine tuned the settings with a much needed gamma correction: http://www.sendspace.com/file/pwakx4

Think I will go with that setting for this particular reel, if you don't want to bother downloading the sample, this comparison will tell you what's been done:

^^ the horror! see the incorrect aspect ratio as well. Alan Smithee was the guy responsible for this DVD.

latest sample:

Subtle but ultimately makes a big difference. You could definitely get a lot better results going scene-by-scene but with a source like this, I definitely won't. This shot of Luke is obviously something that can be improved upon as well but doing so will negatively affect other scenes, so I'm only trying to find a middle ground here.
