3:2 pulldown,and timing question?


a newbie question.yop I am anewbie!!

how are movies on DVD? I mean they are set at 24 frames a second, and the 3:2 pulldown is done by the DVD player?I think it is the right way to do, to save space on the media…am I right?

how done is the timing?.. to go from 30 images/second to 29.97?
if the DVD player read to fast, what is happening?, does it slow down immediately to the right timing, or does it slow down to reach an average “speed” on the remaining movie?
