My solution was quite simple. I am running Windows 10 with an Intel i7 processor and an SSD drive. I changed the destination folder to C:/MainMovie and that was it. DVDShrink failed every time when trying to write to the default destination folder. The name of the destination folder isn't important, but where it located is important. Do not attempt to write to a folder within a system folder. I love DVDShrink with Imgburn. If anyone needs a copy, I'll be glad to share if this forum allows private emails to be exchanged.
