Play Encryted Blue Ray on Pc Free 2018

Summary

Playing an encrypted 4K (UHD) Blu-ray on a computer in a legally unambiguous way seems to require a hardware-level DRM scheme, which in practice means Intel's SGX (Software Guard Extensions). But SGX is not included in 11th- and 12th-gen Intel processors (as well as all AMD processors). From Intel's Alder Lake SDP page (⭕ added) :

This has caused Cyberlink to clarify in PowerDVD's FAQ that:

Quote

It has been determined that it is no longer feasible for CyberLink to support the Ultra HD Blu-ray playback on newer CPUs and the latest Windows platforms.

Cyberlink even goes so far as to caution against upgrading your OS and drivers!

Quote

For users who use an older compatible platform and want to keep the Ultra HD Blu-ray playback compatibility on the PC and with PowerDVD, we suggest you continue using the 7th - 10th generation Core i series of Intel CPUs and motherboards that support the Intel SGX feature. You should also consider not updating the OS (e.g., upgrading to Windows 11) and related Intel drivers to the latest versions in order to keep the Intel SGX feature from being removed from your PC.

The article in Bleeping Computer notes that SGX was deprecated because of all its security vulnerabilities:

Quote

As a secure enclave technology, SGX was commonly targeted by security researchers who discovered numerous vulnerabilities and attack methods

Examples of attacks targeting Intel SGX include:

  • the Prime+Probe attack discovered in 2017,
  • a Spectre-like attack disclosed in 2018,
  • an Enclave attack discovered by researchers in 2019,
  • a MicroScope replay attack,
  • the so-called "Plundervolt" injection attack,
  • a Load Value Injection (LVI), and
  • the SGAxe attack on the CPU cache resulting in the leak of the enclave's content.

In summary, Intel had more to gain from SGX's deprecation from the perspective of security.

Internet commenter Beammeup5 persuasively clarifies that while PowerDVD is "one of the very few officially authorized software vendors for encrypted UHD disc playback," it's still possible to play an encrypted UHD Blu-ray disc on PC, if you use a decryption solution that's presumably not officially authorized (emphasis mine) :

Quote

Intel SGX is not a requirement for playback in the UHD Blu-ray spec. PowerDVD just happens to make use of Intel SGX for their decryption implementation / HDCP handshake enforcement. Other software players that don't make use of Intel SGX can play UHD discs just fine, so AMD CPU owners need not worry.

Just use MPC-HC or JRiver Media Center, etc. Of course, you may need to use "alternate" decryption options like AnyDVD or DVDFab, and naturally you also need a UHD capable disc drive with compatible firmware. like the Asus BC-12D2HT. Many sellers will flash the stock firmware with UHD-capable firmware for drives sold as "UHD ready".

My thoughts

Narrowly, this whole debacle shows that Linus is right to rip his Blu-rays to hard disc: If computers can't play modern Blu-rays without gray-market solutions, then why not just use a gray-market solution to rip them to a more convenient, future-proof format?

More broadly, I have to imagine that this augers poorly for the future of Blu-ray specifically, and physical media generally. Media companies' inability to work with tech companies to preserve compatibility comes off as a huge vote-of-no-confidence in their own ecosystem.

Oh, and — at the risk of stating the obvious — don't follow Cyberlink's advice to avoid upgrading your OS and drivers, unless your computer is air-gapped from the Internet! 😆
