My Macbook Pro will not play a Disney DVD (Howl's Moving Castle). It says supported disc not available but it plays on my cousin's Macbook Pro.

Basically my macbook pro will not play this one DVD. It is a dvd that is fresh out of the package that I order from amazon and it is the second dvd that I have tried. Amazon sent me a new dvd when there were problems but both are not working but my laptop will play all other dvds, including the bonus dvd that came with the dvd i am trying to watch. I tried playing the dvd in my cousin's macbook pro and it worked. I already repaired discs permissions and restarted my computer but i cannot get this dvd to play for the life of me. When I put it in the disc drive the laptop buzzes for a few seconds then spits it out. When I open dvd player before hand and hit play it gives the message "supported disc is not available"
