Hi I am trying to backup 'Perfect Stranger' and have had a few error messages come up. 1. Invalid DVD Navigation structure So I read through the forum and found a suggestion of using DVDFab and followed instructions using DVDFab then DVDShrink should work fine. Which it did and just before it asked for disk to be inserted it came up with this error: 2. DVD Video files reallocation failed 8:49:41 PM #1 Phase 112 File APIProgress.cpp, Line 282 DVD-Video files reallocation started 8:49:41 PM #2 DVDREALLOC -24 File DVDVideoCompilation.cpp, Line 1294 One or more files (mostly VOB file(s)) do not belong to the corresponding IFO file 8:49:41 PM #3 Phase 115 File APIProgress.cpp, Line 282 DVD-Video files reallocation failed 8:49:41 PM #4 Text 0 File NeroAPIBurnFS.cpp, Line 218 Failed to realloc DVD video files Can somebody please help me. How do I back up my dvd??? Thankyou in advance for your help.
