They pirate a dvd and make that dvd have the same exact menu as the original movie dvd and the same options as the original dvd but in widescreen
The only reason i ask this is because i saw a pirate dvd of the dark knight and i want to do that, not illegal stuff, just for a couple of mexican movies that my cousin has.
i think that they woud get the files from the dvd with dvd decrypt and burn them with some program

so the question is how would one do something like that
