![]() This isn’t the first time this has happened, whoever it is that maintains MakeMKV does a good job of acquiring new keys, so usually it’s just a five minute job to download a new version, and then off we go again.

However, these decryption keys can be revoked, and once they’ve been revoked the drives will refuse to use them to decrypt any data, even data from old discs that they’ve been happily decoding in the past. The drive then uses the key to decrypt the data. ![]() Until recently, I’ve been happily doing this using MakeMKV and a Plextor USB Blu Ray drive, but unfortunately it seems that the film industry thinks the best way to reward me for buying so many is to brick my drive.īlu Ray discs are encrypted, and to read one the player (or ripper) software has to pass a key to the drive. As soon as I get a new one, it gets ripped to my MythTV backend, from where I can watch it at any time and on any screen in the house. I buy a lot of DVDs and Blu Ray discs, but I very rarely watch them straight from the disc. ![]()
