Just to follow up, I went ahead and used CloneDVD2 to create a title 1 copy and a title 2 copy. The title 1 copy plays the movie when you click on “Unrated” and goes right back to the menu when you click PG13 The Title 2 copy plays when you click PG13 and returns to the menu when you click unrated.
@Pythonis: I did NOT base my method on time. I just noted that based on the correct method, the unrated was actually the one that displayed the shorter runtime. Re-read my post and you’ll see I checked the title that the player played when I selected each version.
Now for a better question…who has actually watched both and what is added in the unrated version (is anything in the rated that’s not in the unrated)?
