Re: Where can I read about why only some drives can rip, and how AACS for UHD is different that HD?

On my Scarface copy MakeMkv reports "v66" for the HD disk too.

Where can I read about why only some drives can rip, and how AACS for UHD is different that HD?

I've read how AACS works plenty of times, but all the papers and forum posts basically say that's how it works for ALL bluray disks. There is clearly a difference because SGX is only needed for UHD decryption code and even Pioneer drives can rip the HD disk of a v66 bluray set. I have Scarface which...
