Protecting content from theft is the purpose of DRM. Too often, however, it creates more problems than it solves. Modern PCs cannot read Ultra HD Blu-ray discs due to the removal of Intel SGX from Intel’s Core 11000 and 12000 processors.

Intel Breaks 4K Blu-Ray Disc Playback on New CPUs

An issue affecting CyberLink’s popular media player was first reported. In Intel’s latest chips, SGX DRM is no longer supported, leaving only the 7th through 10th generation Intel chips to play Ultra HD Blu-ray discs on PCs.

As a result of removing the SGX feature and the compatibility issues with current Windows operating systems and drivers, CyberLink is facing a substantial challenge in supporting Ultra HD Blu-ray movie playback in our player software. In a customer service post, the company stated that it is no longer feasible for CyberLink to support Ultra HD Blu-ray playback on newer CPUs and Windows platforms.

The decision by Intel wasn’t arbitrary. Researchers discovered numerous vulnerabilities in it and exploitable methods to exploit it. Thus, Bleeping Computer points out, and researchers often targeted it. Intel had to fix these holes.

As a result, the openings left by SGX were not worth closing because the number of PCs watching 4K Blu-ray movies on their computers is likely to be low enough.

CyberLink also speculated that Intel could remove SGX technology from existing processors. If you enjoy watching 4K Blu-ray discs, the company suggests you keep using the 7th-10th generation Core series of Intel’s CPUs and motherboards that support the Intel SGX feature. It is also advised to avoid updating to Windows 11 to continue enjoying support for the technology.

It would help to consider whether you want to keep your computer behind on updates by using a subset of discs. We cannot say whether Intel will take this step, but you can consider using a subset of discs. I would rather have the most recent drivers and operating system, but ultimately it is up to you.
