My understanding is that the line about "existing prints" is misleading bullshit because they wouldn't make a dvd from "existing prints" anyway. They'd create a new source from whatever the best available elements are, or something? The "best available", I guess, would be a 1997 IP or IN, plus the shots that were lifted out in 97? Assuming those particular shots are in storage, and weren't burned on a pyre Vader-style.
