I tried to create an ISO with DVD Shrink (ver. 3.1) but got an error message when the backup process was at 95%, that stated "DVD shrink encountered an error and cannot continue. Failed to write file "VTS_02_1.VOB" There is not enough space on the disk." I have 60 GB free on my harddrive. I have Windows XP and a FAT32 hard drive. I was able to backup the DVD to the harddrive as TS_Audio and TS_Video files and burn it with Nero, but I would like to save the backup as an ISO so that I could use DVD Decrypter.
If you running FAT32 - you will have problems in trying to burn ISO files larger than 4GB. Many solutions and work arounds throughout these forums - just run a search on FAT32
