Intel and Windows 11 Deprecating SGX Breaks 4K Blu-ray Playback
It took a while for this discovery as it's probably rare for people with modern PCs to also have Blu-ray optical drives. Apparently PCs with Intel 12th Gen Core "Alder Lake," and older 11th Gen Core "Rocket Lake" processors, as well as the latest Windows 11 OS, are unable to playback protected 4K Blu-ray video discs, as the DRM component is broken in the absence of Intel Software Guard Extensions (SGX). Intel introduced SGX with 6th Gen Core "Skylake," and deprecated it with "Rocket Lake." To be clear, playback of Blu-ray discs at 1080p isn't affected.
CyberLink, makers of the PowerDVD software that's bundled as an OEM application with optical drives to play back protected Blu-ray video; put out a statement on its website confirming that they're unable to help with this situation, as they don't control the DRM, the Blu-ray Association does. "The removal of the SGX feature, and its compatibility with the latest Windows OS and drivers, has caused a substantial challenge for CyberLink to continue supporting Ultra HD Blu-ray movie playback in our player software," it stated. Just to clarify, this only affects playback of Blu-Ray content at 4K—1080p is not affected.Many Thanks to Steevo for the tip.

But also I have no plans to switch to Windows 11 or 11th-gen Intel, so...
Funny thing is not even the PS4 Pro can play back UHD Blu-Ray, that says a lot about how relevant those are. :laugh:
Fact is I can't even remember the last time I played a Blu-Ray movie.
And those saying "I do not care" could show more solidarity with home theatre fans. It is in everyone's interest that PC users can also enjoy their collections of movies.
But seriously, I don't know anyone who's got a 4K Blu-ray player and the discs, let alone plays them on their PC, so I can't see this being missed.
Honestly, I can't even finish most of the recent movies. It's 50% cringe with the other 50% being lame CGI. There is a huge study by the EU that showed exactly this. Top kek through and through, although it's common sense if you think about it.
so I'll have to rip every 4k bluray disc, meh
But, as i'm a Ryzen owner (which do not have SGX alternative) and a proud owner of Libredrive firmware, i don't care. SGX requirement was a joke and can easily be bypassed by some softwares like xReveal (Free BD Decrypter, just missing keys that are freely available on the web) and once backed up, you don't need a software or noisy drive anymore
They dropped support because too much peoples don't care about BD4K on pc (Most peoples don't have a 4K monitor, it's costly and got stupid system requirements (intel only which become even more costly))
Remember when DVD drive was cheaper (and provided with DVD playback software) than their living room alternatives?
But yeah, most people don't give a shit.
For most people watching movies is just a thing they do as low priority entertainment, not their core activity. In this context streaming is a huge progress for the vast majority of people - convenience is king and the quality only has to be "good enough".
AMD, Intel and BD Association need to step up the game. By removing buggy SGX, Intel dropped the ball as they have not replaced it with next gen solution. There are good options for legit PC UHD Blu-Ray, such as TPM-linked or similar. There needs to be a push to enable a new gen of security, but nothing like DRM. There's got to be the way.
I have PC BD UHD drive and 9th gen Intel CPU on HTPC. I do not want to be forced to buy a stand-alone BD UHD player or rip my own movies just to be able to play 4K collection or ripped files from the same collection. Ridiculous. People will show a middle finger to disk-based cinema entertianment if the industry does not work out easier way to consume owned and legit 4K disks on PC platform. They cannot force people to buy more expensive stand-alone devices for this purpose.
It's enough to have HTPC with capable disk drive, player, 4K TV and decent surround system. It does not need to be expensive and this must be re-enabled in new way. Groups of home cinema fans of UHD disks on PC need to lobby CPU vendors and BD Association and push them for a new solution.
BluRay only uses HEVC Main10, i.e. 10bits for color.
Feels like the same type of error as not having AVX 512 on i9's.
If I watch 4k and look for the differences I can see them, but its definitely far from a requirement for me, at 1080p I can already see all the details I need to see.
Netflix has proven as you said, it just needs to be "good enough" and convenience is king, been able to at a click start watching a movie, instead of buying or renting a disc, and having to get up and insert it into a player. Plus no storage space required on shelves etc.
I am also someone who now thinks stereo is good enough, surround sound speaker setups just aren't worth the hassle, and this is also proving itself on PC where the most dominant setup by far now days is stereo headphones.
