As far as I can tell, every dump of a NUON enhanced movie has "Nuon-Enhanced" under the edition. However, as far as I can tell, none of these are actually referred to as such officially in any capacity, and this edition should be removed from every page to be replaced with their proper editions. They have the nuon logo on the back and whatnot, but do not say "nuon-enhanced" anywhere, and usually have another clear candidate for edition. I understand that this is a very small subset of movies, but it seems inconsistent with the rest of the database, and it also makes the process of matching a given dump to its proper release somewhat confusing. For example, the Bedazzled DVD appears to be from the Special Edition, even though it could presumably also be from the Bedazzled/Scout 2-DVD set without manually searching the barcode (I don't think that version has any Nuon content, but that's also why it's good to know in the first place). I'd assume discs that fall into this category would be treated like hybrid or multi-system DVD-Video discs as usual, and just have "NUON" or "NUON-enhanced" in the comments somewhere, and not in the edition. If this policy is already set in stone, I apologize, but I couldn't really find any previous decision on this.
