dark_jedi,
I'm going to rip them. It's really just bit-perfect capturing if you want to get technical about it.
As for the other mixes you're looking for, I have all of those ld's, but the 1980 empire disc (1425-84) is analog only, and time compressed, so that cannot be "ripped" per se.
I'm going to try to get a copy of 1983 Japanese Fullscreen LD (SF098-0013) because it should have the same mix, but isn't time compressed.
