Page 1 of Vanilla versions

Call me Mr Thicko but can anyone tell me what a vanilla version of a DVD is at all? (and I`m sure there`s loads of you that can tell me!).

I`ve tried searching the net but no joy..as yet..

Put simply it means its a bare bones disc with no (or very little) extras...

Thanks....now I know what it means when I come to buy one!

Since this is a suitable thread (didn`t want to start one off for this) does anyone know the first DVD or series of DVDs to add special features, and the first proper Special Edition/Collector`s Edition with a glut of them. How about the first 2 disc?
