Did you ever use the latest versions of AnyDVD v184.108.40.206 and CloneDVD v220.127.116.11 with whatever title DVD and attempt to make a back up copy of this DVD.
If the latest versions of AnyDVD v18.104.22.168 and CloneDVD v22.214.171.124 were unable to make a back up copy it is most likely because the original copy of the DVD you were attempting to copy had some type of mastering errors other than some type of encryption copy protection scheme when they were manufactured.
Dvdfab decrypter might have ignored these mastering errors and allowed copying of this DVD title but that doesnâ€™t mean that the back up copy you made is a quality error free copy.
Encourage you to check your back up copy you made using dvdfab decrypter and CloneDVD with Nero CD-DVD Speed (http://www.cdspeed2000.com) for errors. Below is a Forum Link that depicts in detail exactly how to use Nero CD-DVD Speed to check for errors. A quality back up copy will be error free.
Just because your back up copy currently plays in your DVD device doesnâ€™t mean that it is error free. The goal of backing up a DVD is to have the most reliable error free copy that is possible. Your back up copy might be playable today in your present play back equipment but that doesnâ€™t mean that it will be playable at a later date and in a different play back device. The goal is to successfully produce an error fee copy that will play in all various situations. Also if your back up copy has unknown errors it might not be possible to make a copy of your back up copy if the need ever arises.
