When I check an original movie DVD (The Beach) with DVD Decrypter it reports the total size as just over 8GB, and when I go ahead and rip, the resulting ISO file is indeed 8+ gigs so I figure I'm dealing with a DVD-9. Now, when I go to use DVD Shrink on it, after analysis it shows the total size as only 4.46GB!! And yes, that's the total size, the whole green bar is entirely green (goes right across the whole screen) with no red whatsoever. And in the details, the main movie is shown as about 3.6GB with the other directories making up the difference. So, why are Decrypter and Shrink reporting drastically different disc sizes for this movie? Which one is wrong?
