I'd have thought the French one runs to 2 discs due to it having 4 language tracks - 2xDTS and 2xDD5.1 in English and French.
As I understand it there's no burnt-in subtitles on any of the releases at all, all subtitles are player generated across all the regional releases.
I did read somewhere that there's some kind of coupon in the original Dutch release that gets you money off this 2 disc one though, don't know how true that is
i would say its on 2 discs just cause of the multiple soundtracks, the listed extras are the same as the usual ones, but.....aaarrrgh i need to get it just incase!!! but i cant afford it so i wont...just yet!
