There are several versions of the DVD running around. For one thing, ONLY the DVD-ROM version is considered "any good". The DVD-VIDEO versions, which run on PS2's and xboxes, are absolute crap...and those are the ones you see selling for $10 bucks a pop.
I dont think its that people hate it, its that most of the versions play terribly..slow..choppy. The DVD-ROM one is the only one that was any good, and last I heard it was pretty hard to find.......
Or you had to order it direct for something absurd like $50 bucks.
