Backup with Protect DiSC v9

Hello community,

Sorry for my bad english but I'm french :tongue:

I have bought an expensive book on amazon with a dvd and I want to make a copy of it to preserve it.

I have discovered that it's a protected dvd and after having used ProtectionId, protection is displayed:

Dvd file scan: Protect DiSC v9.5.0 [Build 0x16008 / 90120] detected!
Dvd sector scan: Disc Protection: ProtectDisc / v 9.0.1103 ProtectCD

I have made a dvd image with the corresponding profile in DT but when I mount this image in ide or scsi, I get the following message:



And after having tried to burn my image :



I can't make a work backup. :frown:

Could someone help me with this protection?

Thank you in advance. :)
