I would imagine there have been lots, giventhat there are thousands upon thousands of discs out there. "Kung Pow: Enter the Fist" comes to mind, with 4 different audio tracks (original unedited audio, 'what they were really saying' audio, book on tape audio, commentary) Is that the sort of thing you meant?

I was looking more for the different versions that Zombie mentioned. I'm just wondering if our concept of what an ultimate disc would be - with multiple mixes - is something that other official DVDs have ever had. Apparently, it's been done before.
