I have just got 6 imacs all with cs4 suite installed, when I press space to play or J or L to play it only plays a milli-second and not the whole thing, all the mac are doing this ? is there a setting someplace ? I also have the same problem in Soundbooth and even final cut, imovie. Anyone help ?

have the same problem in...final cut [and] imovie.
That is pretty strong evidence that this is not an Adobe issue, but a much wider system issue. I'd get in touch with whoever supplied the machines.
