[QUOTE=ObzenX;2555297]Thats not an option since I dont have the source disc. I found a solution.
You can use Pcgedit to create a proper dual layer image which is what I did.
I have the exact same error message – “[I]Optimal L1 Data Zone Start LBA[/I]: [I]None Found[/I]! (VTS_03)” – and the same problem as the OP (I don’t have the disk anymore).
I have the ISO file and the MDS files from ImgBurn, but I don’t have any files or folders to use “build” in ImgBurn.
Is there a way to fix this issue without the original disk and without any other files than the MDS and the ISO file? I have made backups of disks many times with ImgBurn and never had a problem before, so I was mystified when this happened.
