I've just recenntly started backing up my DVD's and decided to use DVD Shrink & Decrypter. I use DVD Shrink to reauthor and select what I want, I always pick just the main movie and deselect all but the audio 5.1 english then I burn with Decrypter. I have read that some use Decrypter to decrypt & encode then use DVD Shrink to to compress the movie and then use Decrypter to burn. My question is, I just backed up Mystic River which is 138 minutes and doing it with DVD Shrink and then burn with Decrypter the best compression I get is 66.4% Is there any other way to back this movie up with less compression??? or is the way I did it the best it gets????
