I'm surprised you're not going for the super-bit disc Guy.
Not certain about R3 discs, but I think it is usually just the cinema showings that are edited - I remember seeing Swordfish with laughable cuts which resembled a 1900's film.
so is there a difference between the R3 and R1 superbit.? I have the Reg 1 as always felt Reg 3 discs were inferior in picture quality, only ever had 2 - Battle Royale and The Others and both had questionable picture quality..
1. R3 are like R2, i.e. every country in that region might have their own release.
2. There are cheap R3 (I call them "local productions") which are crap.
And here I don't mean pirated copies as those are usually R0.
3. R3 releases from the majors (Warner, Fox etc) are usually re-coded R1 and thus you can expect the same quality and no cuts as far as I can tell. Even in Malaysia they contained scenes usually considered offensive.
However sometimes extras or a DTS soundtrack might have been dropped in favour for Asian soundtracks and/or Asian subtitles.
