I've copied several DVDs to my computer using AnyDVD. I've also made backups of these DVDs using Nero 6 (which I later upgraded to the latest version). I simply set Nero Burning Rom to DVD-Video mode and copied everything from the VIDEO_TS folder to the correct folder in Nero (also VIDEO_TS). In most cases, I burned the discs to Memorex DVD+R DL discs. When played back, they seemed to work fine. Now when I try to re-rip from these burned discs it won't work. AnyDVD performs the following steps: 1) processing 2) Repairing defective DVD structure... 3) a box appears with the message "CloneMap 2" 4) after picking 'OK', the rip is Aborted! These discs seem to play fine when inserted into my DVD drive and played with VLC. Has anyone else experienced this problem? Is there something wrong with earlier rips from AnyDVD? Are these memorex DVD+R DL discs are becoming defective over time? Is the DVD-Video burning feature in Nero creating a defective DVD structure? Do I need to set the file system to something other than ISO? Is anyone having better luck with CloneDVD? If so, does it work well with DVD+R DL discs? Any help is greatly appreciated.
