Truth be told, the majority of purists clamoring for "unaltered" versions don't realize what they're asking for, in the strictest sense. If Lucas were to release a truly unaltered version of the OT, it would be grainy, dirty, color-drained, and the sound would be seriously degraded. That's what "unaltered" means: not changed.

This guy's got his terms wrong: "grainy, dirty, colour-drained with the sound seriously degraded" isn't unaltered but unrestored. And seeing as how we call for a restoration of the unaltered version, I don't see how anyone could be confused.
