I use DVDBackup and Toast to burn DVD-Rs on my G4 Mac and most single layer discs work fine. I also use DVDBackup to copy other region DVDs to the hard drive so I can watch them on the computer without having to change region settings on the drive. However recently I have found several discs which won't be processed by DVDBackup. These include Visitor Q region 1 Texas Chainsaw Massacre 2 region 1 I Spit on Your Grave Millenium Edition region 1 I get the message Decryption Problem Failed to decrypt Video Title Set 1. Skip it and continue, or stop processing? Then after skipping each time I get the message I get this message File System Error Error in processing file 'VIDEO_TS.VOB'. Continue processing other files or stop now? Which when continued it repeats this error for most of the VOB's until it is finished decrypting what it can. Is there a new encryption that needs to be cracked and is there another program for Mac I could try to do it. Thanks
