That's a good way to start with. :iagree:
I'm using the re-author function in Shrink when lazy. Running a loop with analysis can sometime improve the quality of copyed movie even more.
Working with images (ISO) also gives you the choice to burn with ImgBurn/Decrypter and you can backup a whole movie with excellent quality only using free-tools!
The bad thing is, DVD Decrypter is not updated anymore and I've been forced to use AnyDVD lately.
