I decided to move this to a separate thread. I have an lg BE16NU50 drive. It rips blurays at 24 mb/s, but it only rips UHD disk at .5 mb/s. I received a uhdkeys.txt file from this forum and someone else pm me with a file too. I don't know if it's the drive, the fact that my Mad Max fury road disk is looking for a different key than the one in the file, or a bad disk. The firmware is 1.01 and I haven't touched the firmware at all. Here is the log file. Hopefully someone can advise me on how to proceed.
