I have a little over 700 DVDs and want to back up just the main movie uncompressed. I've been using DVD Shrink or Decrypter for making backups of my movies uncompressed. Some movies I can fit the entire disc and menus and some I only get just the movie with no compression at all as I have a 92" screen and want full quality. Now by using either shrink or decrypter when I make uncompressed copies are they identical to the originals? Should I bother making backups or just keep the real ones? I've watched my copies and they look good just dont want to short change myself. Thanks in advance.
