DGENTERPRISES,
Recommend you try what dmp31 advised. I've been burning DLs with
AnyDVD and DVDD for 2-3 months with absolutely flawless Bkups and no coasters. I also did Revenge of the Sith with v.5.6.1.1...so as others have suggested...what you're experiencing is not a decrypting error. Some folks using Fab reported similar errors, these seemed to be related to compression issues.
