i recently bought my macbook pro and have been absolutely loving it. yesterday i ripped some of my dvd's using mac the ripper onto my computer. for some reason when i attempt to open "shutter island" under file>open dvd media, the movie will stutter at the beginning and then play. the only problem is the dvd player will lock up and i will get the spinning beachball any time i move the cursor over the application, remote control for it, or the menu bar at the top of the screen. because of this i am not able to put the movie in full screen, minimize it, pause it, fast forward it, etc.. anyone know how to fix this problem? i dont know if it makes much of a difference, but the app version is 5.3. thanks!
