The best way to tell - if it has Chinese subtitles then it's a Chinese copy.

I noticed on the chinese version, the subtitle menu only has selections for english and korean, but during the movie another is available.

Sound Delay
 

Did anyone else notice the sound delay on The Last Crusade? It was especially obvious during the scene when Indy is trying to smash the floor in the library as the librarian is stamping the books. The crash noise is supposed to happen at the same time the stamp hits the book, but is delayed. So the crash noise happens while the stamp is still in the air, pretty funny...

I didn't notice a sound delay on my copy. The stamp and crash were in synch.
Disc-Flipper - I didn't see any pixellation on my copy (Korean). However I haven't seen the Chinese versions so I couldn't make any educated comparisons.

The new Indy set has not been released yet...and we don't know when it's happening.

It's on hold right now.
