I have unsuccessfully tried to backup Khartoum (starring Charlton Heston) many times, using three different Khartoum disks, including the movie I purchased, and the ones purchased by two friends, all purchased from different stores in Western Australia at different times. Firstly I used AnyDVD 18.104.22.168 with One Click DVD Copy Pro 22.214.171.124 and failed with all three versions of Khartoum. Next I used the anyDVD ripper and it failed with all three versions of Khartoum. Ironically, the reported failures for all disks were at 51% of the disk read, and a read error was reported. All three reported read errors occurred in file VTS_02_04. This makes me think that perhaps there was a production error with the hardware by the manufacturers when making the copies of this disk for Australian distribution, rather than a new type of protection. I am going to try with anyDVD 126.96.36.199 but I do not expect any difference. Has anyone ever successfully backed-up Khartoum?
