Hello, I've been backing up and playing BD for many years using the software but I recently updated my home system to support UHD. Maybe I was overzealous in backing up my media and made a mistake somewhere. I did a backup to .iso and used the same settings I have for my BD catalog. The UHD rip appears to have worked fine and completes in full. So, I have backed up several discs already and when I attempt playback, they all freeze at a black screen before loading the menu. I see in the sticky posts that this may mean that RedFox needs the log file to add the correct key. I would think that my discs were already in the database considering some are older titles. Here is a list of UHD discs where this has happened: The Hunger Games (all 4) Frozen 2 1917 Knives Out Star Wars - Episode 9 Am I missing something or just have bad luck that I've picked titles/discs that are currently not supported? Thanks!
