So, I just got the japanese PIBF-1001 DVD from Terminator 2.
First of all the movie is split in two sections on one side. Seems to be splited where the layer break is.
From first viewing through some scenes, I would say that is is color wise not different from the US release, but I could be wrong. At least the difference is not noticable during first checking out and remembering the color of the US discs…
Edit: Just Checked both japanese DVDs side by side: Both have the same Video Master.
