Dual layer and PCM sound were not necessary or wanted for the Classic Editions, since the actual 2004 DVDs are actually of single layer size once you remove all the alternate audio and other crap, and they're encoded with -- wait for it -- AC3 sound.

They're based on the 2004 DVDs, so yeah, single layer and AC3 and Empire and Jedi in particular are flawless. Without flaw.

A Dual layer version of Jedi exists, because it's a longer film and I wanted to preserve the original 2004 version of it. But the single layer isn't yer ugly "looks shrunken" DVD. I defy you to tell the difference, even on a huge screen.
