PhotoAcute Website
It uses several low res images to produce a high res image. For example, if you rip the laserdisc twice (or three times), then you have three captures of each frame, and you put the three images into PhotoAcute, and it produces a high res noiseless image. For example, for each pixel it compares the three low res images, and if two of them have the same color on the pixel, but one of them has a different color, then it concludes that the "odd man out" must be just noise, so it keeps the good color and throws out the noise.
Anyway, they have some examples on their website, and it looks very promising. I believe the Mars probes used something similar in order to produce high res images based on several low res images of the same terrain.
Best of luck to you, I'm looking forward to the X0 release!
(don't start all over again with the new software though)
