Newer Columbia dvd's use bad blocks to crash programs (like DVD Shrink). DVD Decrypter gets around this by replacing bad blocks with dummy sectors. These dummy sectors also crash DVD Remake. After loading the dvd files in to DVD Remake you have to delete (hide) the first block of the main VTS. This is usually the one that was replaced with the dummy sectors. If you don't then DVD Remake will crash. Their may also be other dummy sectors that DVD Decrypter added which will also need to be removed. Their are several Columbia dvd's that will cause this along with a few of the Universal titles.
