What's the difference between Pirates of the Caribbean 2-disc collector's edition and the blu-ray version?

I know that blu-ray is better quality. I'm just wondering in terms of special features, which version has more? Or are there certain features that pertain only to the blu-ray or only to the 2-disc collector's edition?What's the difference between Pirates of the Caribbean 2-disc collector's edition and the blu-ray version?
I don't have the 2 DISC VERSION but all the features on the 2 disc version are on the Blu ray as well. The blu ray has the following exclusive extras: Dolby HD Digital, the main feature is in 1080p as opposed to 480i, There is an exclusive Blu Ray game "Liar's Dice" that is in HD so its a BR exclusive, Movie Showcase ( on most Disney BR) allows you to access certain scenes and experience the HD difference there are also seamless menus,



Does that help.What's the difference between Pirates of the Caribbean 2-disc collector's edition and the blu-ray version?
The DVD and Blu-ray have very similar features. The Blu-ray will be more expensive and on a 1080p display will look amazing. The Blu-ray only plays in Blu-ray player, though.



The 2-Disc Special Edition DVD will play in a DVD or Blu-ray player, but it does look as spectacular as the Blu-ray Disc in either machine. It is likely available for half the price of the Blu-ray though... and even cheaper used in great condition.
