I know there's a DVD Shrink forum but this is a pretty basic, newbie-ish question. When using the full-disc backup option with DVD Shrink, I selected the option to create an ISO image instead of burning immediately or creating the video.ts hard-drive type files. However, Shrink produced three .VOB files instead of any ISO or MDS type ones. Why? I'm certain that I selected ISO, and I got VOB instead. What did I do wrong?
