I'm pretty sure it's a standard DVD but I haven't checked...
one thing that bothered me is that the 2 soundtrack discs don't come with a track listing... I wanted to rip them to my PC so that I could listen to them in my car with my Zune but none of the online track labeling services had the track lists and I couldn't find any material included with the game that told me what they were... considering there are 42 tracks (I think) that's a lot of manual entry...
