The laserdisc has two significant things about it -- since it's the *original* director's cut, and all the official releases are *re-created* director's cuts, any mistakes in the recreations wouldn't be in here -- and can be discovered by a comparison. (I'm sure everyone knows that the Anchor Bay version has a few mistakes and missing shots in it -- right?)
Also, this laserdisc is fullscreen -- and since AOD was shot open-matte, that means that this disc actually has *more picture information* than the recreated director's cuts, which are all cropped to widescreen.
So, no "new material", but it's got more picture information than any director's cut currently available, and a mistake-free roadmap of what the director's cut really looked like.
