Get a DVD onto my iPhone Is there an official way to take my DVD and put it on my iPhone?
There isn't an "official" way but a common and easy method is to rip the DVD with a utility like HandBrake and then drop it in iTunes to sync with your iPhone. The US Supreme Court ruled that 


  nothing in the agreement prevents you
  from making copies of DVDs. Nothing
  requires that a DVD be present during
  playback.


So yes, it is legal. source
