Well, that explains it, thanks. They didn't explain why to me. I did know they buy a lot though. [The discs in question were accidental "gifts" from amazon.com. They told me to donate them to a library. Still have two large boxes of them, all brand new, BDs too.]
Actually, Canadian and American...
^ Umm, most of the extras they put on the first BDs, and still to this day in some cases, came from the previous DVDs. Your library needs a better "quality" of donor! Or maybe the library takes the extras disc out, it may be unrated stuff they don't want to deal with.
Actually, I don't know how...
