I bought a movie on my Iphone4s, but I can't transfer it to my computer

I have a macbook pro, and I tried syncing my iPhone to my computer, but its not showing up on my movie library. What do I do to get the movie on my computer?

Make sure everything on your iphone and computer is upgraded, have you tried syncing it on another computer? Have you also tried syncing other things on to your computer? If you tried syncing other things on your computer, it is the movie's problem. However, if you are able to sync it on another computer, upgrade everything on your macbook pro.bit.ly/UUsbu9
