Movies for 2D simulations are encoded with MicrosoftRLE and should play in any standard media player.
Movies for 3D simulations are encoded with Microsoft Video 1 for better compression, and should also play in a standard media player. We recommend QuickTime player from http://www.apple.com/quicktime/download/.
