content: I for one am very dissapointed with the so-called "Extreme DVD" edition that was released this year.The Ultimate Edition is arguably one of the coolest DVDs ever released but this newest edition is hardly the extreme DVD that the title says it is.The extra content that is on here is newly recorded commentary by James Cameron and his crew. While the commentary is good, it only works on DVD-Rom drives, something which I don't have but a friend did. You also lose a lot of the awesome new features on the Ultimate Edition.T2 is great but the Extreme DVD is a waste of time. Avoid it. Go for the Ultimate Edition.
