Hi. goreguts, for more advanced editing with DVD Shrink, I'd suggest you look at the following guide. http://www.dvdshrink.info/reauthor_intermediate.php
goreguts I first use DVD Decrypter to decrypt the whole movie into a folder. I then use Roxio Easy Media Creator 7 (copy dvd) feature and select only the main movie to be burned to the dvd
Most backup software has a movie only funtion just choose that. To do it with the freeware DVD Shrink choose reauthor, drad and drop the main movie in the window to the left, deselect unwanted audio tracts and hit backup.
