I have the latest version of Ulead Movie Factory 6+ which supports HD & BD. I used the "Burn Now" utility to create an ISO image of a BD movie (with AnyDVD/HD loaded). The image was perfectly created without any error. I then mounted the image to a Virtual Clone Drive (again from Slysoft) with out any problem. It was my intent to store ripped HD & BD image files in this format for eventual burning, but when I attempted to "Watch" the movie mounted on the Virtual Clone Drive with PowerDVD 7.3 I received an error message "Unsupported File Structure." Does anyone have any idea what is going on here? What is even more odd is that I then was able to Rip the Virtual Disc to a folder using AnyDVD/HD Rip BD feature which I assume means that the file structure was correct. Any help or suggestions would be appreciated.
