I have tried to backup two movies with DVD Shrink 3.2 with my Windows 7 (tower) computer, but as soon as I try to open the drive with the movie I get "DVD Shrink encountered an error and cannot continue", "Copy Protection Error", "Incorrect Function". I then tried to backup the same two movies with my laptop running Windows XP and everything works perfect. Does Windows 7 perform some check on movies that causes the copy protection error to occur? I searched through the forum but did not see anyone else having this problem, but did see several places stating that DVD Shrink does work with Windows 7. Any guidance would be appreciate, thank you.
