When using DVD Shrink, I notice that quite a bit is being shrunk and I can see the difference in the video quality from the original and backed up copy. I use DVD Decrypter, DVD Shrink and Nero. I would like to take one movie and split it in half and copy one half to one DVD and the other to another DVD. This was easy with Curb your Enthusiasm, because the DVD had six episodes and each episode was a seperate file on the DVD. I used Shrink and dragged over 3 episodes at a time.
