Intel page confirming SGX deprecation in Alder Lake: 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! Media companies' inability to work with tech companies to preserve compatibility comes off as a huge vote-of-no-confidence in their own ecosystem. More broadly, I have to imagine that this augers poorly for the future of Blu-ray specifically, and physical media generally. 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? Many sellers will flash the stock firmware with UHD-capable firmware for drives sold as “UHD ready”. 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. Just use MPC-HC or JRiver Media Center, etc.
Other software players that don’t make use of Intel SGX can play UHD discs just fine, so AMD CPU owners need not worry. PowerDVD just happens to make use of Intel SGX for their decryption implementation / HDCP handshake enforcement. Intel SGX is not a requirement for playback in the UHD Blu-ray spec.
