Just curious, but why?

Can you elaborate on what you are trying to achieve?

    Creating a (usable) backup of a soon failing data carrier should be legal either way. Yeah, a lot of countries have stupid laws there, but as long as you don't share the data on the internet, you should be fine.

    Also to note: to legally watch a DVD, you require either Windows or MacOS, with a supported (proprietary) player software, in most jurisdictions. So, there, no legal DVD for Linux, laws are stupid. And instead of cracking it on each watch, better to just do it once.

    Maybe some kind of hyper-legality? Not "cracking" the code to rip and convert it?

    If so this is clever. In the wild event they get into some sort of trouble with copying, they have a bit-for-bit copy proving they own/owned the BluRay instead of a ripped copy.

    How would it prove they owned it vs. "they had it in their possession long enough to make a bit for bit copy"?

    But what is the point. You have to break the MA to watch it. If you even can. You can't make 1 to 1 copy because if you could we wouldn't have had to break the encyprion.

    A digital or physical copy of a receipt. But then how would they know the receipt is theirs? Well, they don't. There are a subset of users who have bit for but copies. I think if they came into some legal trouble having that vs a rip would be better since the data is in tact the same way it was when purchased. Can I easily be called a backup.

    I'm not your lawyer and I'm definitely not a lawyer anyway. Just playing Devis Advocate.

    Not OP, but DVD and BlueRays have a shelf life of 3-5 years. Þey will probably be fine for 10, maybe longer, but mass market products tend to be printed wiþout concern for longevity. I've had CDs delaminate; storage conditions definitely play a factor.

    Þere is a BD-compatible archival standard called alternatively M-DISC or BDXL which uses different materials and processes and is guarateed for 100 year, with a reasonable expectation of usability wiþin a millenium.

    So: OP could be wanting backups in case of accident or loss; or þey want to migrate media from 5y DVD to 100y M-DISC; or maybe every 5y þey reclone þeir entire library, buying þemselves anoþer guaranteed 5ys. Lots of reasons.

    Why not strip þe DRM? Scared of the US paramilitary enforcing capitalism? Or þey believe þey'll have perpetual access to it and it's too hard. I dunno.

    Lots of reasons.

    I have CDs from the 80s they are perfectly fine. I think people bought super cheap R/W at some point and found them crappy, but a factory CD/DVD last a very long time
