I am trying to back up some movies i have and my two LiteOn’s will not shrink them with DVD shrink. It says that the sector is encrypted. When i place the same exact disc in my Plextor PX-716A, it will backup fine. Anydvd log shows that it recognizes the disc and has found and removed protections but it will not backup. Is this an issue with the drive or with the software, has anyone experienced this problem?
