On-the-fly decryption software enabled

[Librewhat]

Been using MKV for a while and never had this pop up before, does anyone know what this is or why it popped up?

"It appears that you have on-the-fly decryption software enabled. MakeMKV should process discs with the most sophisticated protections without help of any 3rd party decryption software. In addition MakeMKV works faster and more reliably when it decrypts data by itself. It is highly recommended to disable such software and restart the application.

Do you want to continue anyway (errors may follow)?"

I don't have any other software, 3rd party, trying to decrypt. Been using MKV the same each time but this time I get this message. There has been a recent upgrade for MKV, I wonder if that has something to do with this?

Maybe the disc is a backup disc and no longer encrypted?

[thetoad]

are you working on an ISO or a physical disc?

[Librewhat]

Physical disc.

Is it a DVD? I think the detection goes off, when there is something in brackets in the title manifest of the DVD

[Librewhat]

It was a DVD. I have since copied another and this time no message like this. It must have had something to do with that particular disk.

Im also experiencing exactly the same problem.

My source is soft Bluray files. Anyone, please advise what software suppose to check and disable as 'On the Fly Decrypt' software.
