You know, I didn't think of it that way. Though if that is what was meant, it probably should have been made clearer. If someone bought the laserdisc expecting to get extra footage, like, say, the Hanging David scene from hoDS, and all they got were the snippets of deleted scenes in the NoDS trailers, I suspect they would have been sorely disappointed. Though those of us who love NoDS love every one of those snippets, no matter how short. But then, speaking for myself, I've never seen them as "extra footage."
I mean, nowhere are snippets in the trailer on the NoDS DVD described as "extra footage" - and it's a good thing that they're not. Possibly referring to the snippets that way in 1994, before the deleted NoDS footage had been recovered, would have been one thing - but I suspect that referring to the snippets that way in 2012, when Warner Bros. refused to allow any of the recovered footage to be included in any way on the DVD, would have prompted more than a few NoDS fans to storm Warner Bros. with firebrands and with threats to burn the place down!!
Or maybe they would have staged a mock-hanging in effigy of the Warner Bros. exec responsible for not allowing the footage to be used - that seems more appropriate!!
