Election DVD

I am currently using AnyDVD with CloneDVD and when I was trying to make a copy of Election there was a block of data that was unreadable. It wasn’t multiple blocks of data but just one. The same thing happened when I tried to make a copy of Kolchak: The Night Stalker. Has anyone encountered and similar error, and if so, how do you remedy it? Do I have to use a different program to beat the encryption?

What verion of AnyDVD do you have? Are the DVD’s disc’s scatched?
