Question About Crazy Taxi Daily Radar Movies

Hi,

I downloaded all three of the Crazy Taxi movies from Daily Radar\'s site but what concerns me is that the actual game is jerky / choppy, compared to the dreamcast, it doesn\'t seem ultra fast like the dreamcast version.

Could that be because basically it isn\'t or because the movies are filmed at 30 fps where the game is actually running around 60 fps ?

The preview did mention there would be slow down like in SSX the thing on the video isn\'t really slowdown though it just doesn\'t seem very smooth.
