"UK HDTVs more commonly display 720p and 1080p images at 25fps, while US screens run to 30fps. In each case, the result is a movie that plays faster, with sound at a higher pitch, than it would in the cinema."

I find it hard to believe that North American HD-DVD and BD players are speeding up films by 25% because they can't do the hi-def equivalent to 3:2 pulldown.
