The VUK method needs an older drive that only uses AACS 1.0. DeUHD can use a couple of drives that officially support UHD BD and AACS 2.0, so probably they've found some kind of a workaround (the demo version of DeUHD did work with that drive). I had the same issue with the Buffalo drive recommended for DeUHD. Both of us have direct line (as in among other things working mailboxes for the staff) to the staff and we'd know if they had. Many of you may know Redfox 1 and myself from the Redfox forums and i am pretty damn sure they DO NOT have any valid host certificate. Someone on forum Z said you could do it' after spending lots of cash to get the needed hardware, and having to disappoint the users. No software developer wants ppl to rush over to their support staff / forums with 'hey, decrypting UHD title X using software Y doesn't work. So, before you go make claims as to ANY party (whether it's RedFox or someone else) has a valid host certificate but are deliberately hiding it, make damn sure you've got the proof to back it up. James (Lead Anydvd developer) said it himself that he only added the VUK method to keep a minor batch of ppl happy, including himself. If redfox had a certificate i'm pretty damn sure they wouldn't be using a half baked solution such as the VUKs.

You seem to be severely underestimating how difficult AACS 2.0 is and it's requirements (and dependencies like Intel SGX for certain playback methods). I'd also love to see your proof to where ANY redfox staff member said they had a certificate, or proof to your claims that they had one but are hiding it. AnyDVD uses a similar approach as other tools to decrypt UHD titles based on the VUK's in the config file. The VUKs are useless for you until an AACS 2.0 certificate is made public (or Redfox/MakeMkv/Dvdfab stop pretending they don't have one already)įirst of all the VUK are NOT useless if you've got an UHD friendly drive. You can probably use DeUHD with that drive which will cost you another few $100.
