On the fly decryption problem

[kakkalla]

Hello all. This is my first post here.

I have 25 Blu-Ray movies that have been ripped to my hard drive in order to to preserve them. My grandson has managed to destroy eight of the Blu-Ray disks.

Prior to using Makemkv, I was using DBDFab to clone my disks as .iso files. I have been playing them back using Mac Blu-ray Player (Windows version). I was cloning because I could never work out which title to rip to the drive when multiple titles had the exact same length etc.

Then I thought that I could conserve some hard disk space by re-ripping the iso files using Makemkv so that only the main movie sits on the drive rather than the cloned version of the disk. This I can do for all of my movies from the original disks but not for the eight that no longer work.

When I mount any of the iso files, I get the error:

"It appears that you have on-the-fly decryption software enabled"

In other posts, I read that AnyDVD mights be the cause of this problem. However, I have checked to see if this program is on my PC but it does not appear in the list under the Control Panel>Programs and Features.

I thought it might be DVDFab causing the error so I deleted that from my machine. I restarted my PC but the error is still there.

How can I find which program is causing this problem for Makemkv?

Thanks in advance.

The error is warning you that the ISO file was made with an application which may have introduced errors.
