Getting an error with Dvd shrink 3.2



I recieved a nec 3500 for xmas. I installed dvd shrink and updated the firmware (one made or atleast put out by someone named ziggy?) I am running into some problems. I let it do its analysis of the disk and then click the actual movie section, not the menus, and hit backup. From there I just leave everything and start. A message pops up saying “Copywrite protection error” followed by something about an error occuring with the I/O device. What is going on?

If anymore info is needed to help just let me know. I really have no preference in ripping programs so if there is one that may rid me of this problem please let me know.
