I AM USING DVD DECRYPTER AND WHEN YOU HAVE TO CHOOSE ISO THEN READ INORDER TO VERIFY SIZE TO BE NO MORE THEN 4,718,592,000 BYTES MY DVD MOVIES IS ALWAYS MORE,BUT WHEN I USE DVD SHRINK I NEVER REMOVE OR ADJUST ANYTHING FROM THE ORIGINAL MOVIE AND IT BURNS FINE,QUESTION..DOES THE DVD SHRINK PROG. SHRINK THE MOVIE DURING THE ANALIZING PROCESS? WHAT DOES THE ANALIZING PROCESS IN DVD SHRINK DO TO THE DVD MOVIE? JUST CURIOUS!
DVD Decrypyer doesn't apply compression but in File mode you can select Movie Only. DVD Shrink 3.0b reads the DVD and applies compression auromaticaly (which you can undo). Shrink 2.3 doesn't apply compression until you select what and how much compresion you want.
