I'm trying to make a backup of Futurama Volume 4. DVDs 1&2 worked fine on DVD Shrink. DVDs 3&4, however, crash about 75% through the "open disc" analysing and give an error "sector is encrypted". Anybody else having this problem arise? I will attempt Decryptor to see if it will help, but I really prefer to use Shrink as my program of choice because it decrypts, shrinks and burns.
