I can do digital rips of audio tracks from LD, though I'd only be confident of doing it with an AC3 track - the reason being, AC3 is broken up into packets of a fixed length, so it's easy to tell when there's been a cut-out. I wrote a bit of C to scan through the raw recording and reconstruct the AC3 file, and if there was a skip, I could work around it or just re-record that side until it came out perfect. If I was to try the same with a PCM track, it might well have (very small) skips, and it would be hard to tell they were there.

That, and I only own the Special Edition laserdiscs which nobody wants
