> Digital movies on DVD and Blu-Ray discs on our shelves.

It actually already got a bit more fuzzy with Blu-Ray and especially with later BD+ doesn't it? You own some encrypted data, but there is absolutely no guarantee you will always have access to a player with the right keys and a TV that is compatible and isn't refusing to play it.

It already drove the needle way past acceptable copy protection, do not buy Blu-Rays!

Buy this definitions, DVDs are also problematic, given they're also encrypted.

Blu-rays are universally cracked by this point, so I fail to see the problem. MakeMKV is not going away to the point you won't be able to rip your blu-ray.

UHD blu-rays are a different story, since they added more encryption.

no the difference is CSS (the encryption of DVDs) has been broken, but AACS of Blu-ray has never been broken itself. Cracking it relies on player keys being leaked and those are getting rotated in newer disks, that's what I was hinting at. They also do some ridiculous stuff with obfuscated virtual machines in BD+ and audio watermarking that may mute your ripped disk on newer TVs (I'm not joking[1]). So again: don't buy blu-ray either!

Yep, this is the reason I was an avid DVD collector, but when the Blu-ray switch happened, I never rebuilt my collection.

Looks like I was wrong. Fair enough.
