Therefore, a LibreDrive will never refuse to read data from the disc or declare itself ‘revoked’. Typical example is LibreDrive, an optical disc drive (applicable to DVD, Blu-ray and UHD) intended for accessing disc data directly without any restrictions or transformations enforced by drive firmware. Though unable to be used with official software, such 4K UHD drives allow any software with a regular AACS1 host certificate to read UHD disc data. In fact, those hardware restrictions, because of a flaw in SGX, might just lead to someone cracking AACS 2.Normally, Friendly 4K UHD Drives refer to regular Blu-ray drives that can read BDXL media but do not implement AACS2 protection.

There are lots of people out there, myself included, that would buy a PC/Windows UHD solution in an instant if the hardware restrictions were not so stringent. IMO, the Blu-ray forum, with such restrictive requirements, is just shooting UHD Blu-ray in the foot. I won't get into specifics other than what I already said, but those details can be found on the AnyDVD HD/MakeMKV forums if you care to look. I don't know that this drive will be compatible, but if you have a 'compatible' drive (that can be flashed with unencrypted firmware), a combination of MakeMKV and AnyDVD HD could possibly support UHD playback. You can see Cyberlink's requirements here.

According to the Blu-ray Forum (the official source of the Blu-ray standards) official UHD playback requires Intel's, now no longer included with new Intel processors, SGX (which turned out to be a train wreck of hardware security issues) 'Software Guard eXtensions', and only Cyberlink's PowerDVD supported it - but not anymore. Click to expand.UHD Support on a PC under Windows is a slippery slope of no longer supported hardware - at least in an official sense.
