"on-the-fly" decryption software

Post by CRCCLT »

Hi, sorry if this has been addressed. I searched for "on-the-fly", but didn't find anything. I have been using MakeMKV for years and love it. Today, for the first time, I got the message below.

- What software could be interfering? I haven't installed anything lately and as recently as three days ago it worked fine.
- If I cannot identify/turn off the conflict, am I good to continue? What is the likelihood of errors/what will they look like?
- As background, I just bought the six-disc blu ray set of the Alien movies and that is what I am trying to rip (this happened with the first disc - Alien).

Thanks for your help.

It appears that you have on-the-fly decryption software enabled. MakeMKV should process discs with 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.

This is not the first time this exact question has been asked... Searching for "on the fly" doesn't work because the software does not index words shorter than 4 characters.

viewtopic.php?f=1&t=22799 asks the exact question in 2020, with no real resolution. MakeMKV is detecting something trying to decode the disk while it is trying, so it complains. It MAY be Windows running DVD software; do you have something like that installed?

I'm on a Mac (should have mentioned that). And I misremembered about not installing anything. I installed What's App for Mac over the weekend. I have uninstalled it, and rebooted the system. I'm still getting the message, but I pushed forward with the rip. It seems to be working (no additional messages/errors), but very slowly (what would normally be a 20 minute rip is now pushing 40 minutes and says there is still 20 to go.

I don't mind it taking longer as long as it works.

Thanks for replying.

Sounds like a fake disc that was already decrypted and then burned then sold to you

Huh. Interesting. I got it off eBay and the packaging looks very authentic, but now that you mention it, the data side of the discs does look different. I didn’t think much about it until your comment. But yes, I think you may be right.

When I proceeded with the rip, MakeMKV said it was treating it as unencrypted and it still ripped.

Thank you.

Just had this same warning with a copy of 1989 the punisher. bought from ebay from rare film shop. never looked at the disc before popping it in my player, just chucked it in and went to rip it and the message came up.
after seeing this post and how it could happen with a forgery I took the disc out and lo and behold it's a blue burnable disc with a silly paper label on it.
First time this has ever happened to me on ebay or with rare film shop, whom I have bought very many blu-rays from in the past. very sad to see.

Yeah keep an eye out for fake blu-rays.

Thanks for the post OP

Is not possible the message pops up for region free DVD and Blu-Ray?

Was this issue ever rectified?
I have used MakeMkv for ages with no issues, but suddenly this started happening after an update.
I have a fast Windows computer, a brand new Bluray and no programmes running in the background.
I have uninstalled MakeMKV and installed the latest version after a restart. It still happens.
I have ignored the warning and continued to use the software with no faults showing themselves but it is annoying and seemingly incorrect.

It's not an issue

The issue is your setup or fake discs

I have quite a few region free DVD and Blu-ray discs and I haven't seen the decryption software warning unless I'm using a 3rd party decryption tool. My understanding is that MakeMKV shows this message in response to the presence of certain folders created by tools like AnyDVD ("ANY!") and DVDFab ("FAB!") which indicate that AACS has been removed.

There is an easy way to check what might be happening. Have a look at the contents of your disc within the Windows file explorer. On a standard, AACS-protected Blu-ray disc there should be at least these three folders:
- AACS
- BDMV
- CERTIFICATE

If there are any other folders or files I'd recommend posting the names here or searching online yourself to determine if they are associated with some other decryption tool. If a match is found, you can be confident that your disc is a counterfeit and the warning is working as intended.
