If your VSO product says your disk is protected, then you need to install a decrypting tool that will remove the protection.
Here are some decrypting tools:
free too for DVDs
- AnyDVD HD
by SlySoft (Recommended)
- Passkey for Blu-ray
How these tools work:
When the decrypter is running, it works as a background process, making the disk readable so that software or you can access the contents directly. Without a tool like this the contents of the disk cannot be seen.
***Make sure legally you are allowed to use these software products in your country in order to make your own personal copy.
(As a French company we are not allowed to create software that removes the protection from disks or other digital content).
