So I've been trying to backup the movie 300 but every time I try my computer freezes and the speakers emit this high pitch tone.  It hasn't done this with ANY other movie so far that I've backed up using DVD Decrypter.  I also tried DVD Fab Decrypter AND the update DVD Fab HD Decrypter and in all 3 cases I get the same problem.  I've never seen this with a movie before.  I am running Windows XP with all the latest updates.  Any ideas?  Is this a new dvd security feature to prevent ripping?
