I've been trying to back up Not Another Teen Movie with IFOEdit and XP. I have tried Ripping it with Smartripper but it comes up that it will take 40 hours so I used DVD Decrypter. I followed the guides that are avaliable but when I try to play it in IFOEdit It says NO VALID DVD VOLUME COULD BE LOCATED, this is not the problem as I have read elsewhere in this forum but if I choose to continue it plays the introduction to the film the says DVD WARNING-COULD NOT OPEN A FILE ON THE DVD DISK, IF I continue the next message is A FILE ON THE DVD DISK COULD NOT BE OPENED. PLAY BACK MAY NOT CONTINUE. After that it does nothing. HELP! Coach.
