Offhand, I remember the documentary title was longer than the movie. So, by default CloneDVD will select the documentary to backup. Deselect the longest title (documentary) and then select the second longest title (movie). This should work. Glad to know I wasn't the only person to watch this movie. Good movie. I asked questions myself that no one else could answer when it was released. Edit: This thread doesn't belong in the AnyDVD forum. Though the original poster didn't say they were using CloneDVD I'm assuming they are.
