I tried to backup the grudge and I have dvdxcopy express, It keeps on coming up with a error. what do I need to do
Try using in conjunction with AnyDVD (free 30-day trial) or rip with DVD Fab (free), create an iso with DVD Shrink (free), and burn the iso with DVD Decrypter (free).
Xcopy cannot do this movie, the only way is as suggested using AnyDVD in the background to break the encryption. You can try this program free for 21 days from http://www.slysoft.com Or using the free programs such as DVD Decrypter or Fab Decrypter and then using DVD Shrink to compress.
The Grudge is old news -- there's no special protections on this movie. DVD Decrypter can handle it smoothly via Mode, File F. Other cracking engines that can handle this easily are DVD43, AnyDVD, DVDIdle Pro, DVD Region+CSS Free.
