Hi, I recently bought the Hobbit and LOTR UHD 4K HDR DVD box sets. I guess they were released around December 2020? Anyway, so far I have backed-up and ripped 5 discs. The process I am using is: Insert physical disc Enable LibreDrive Use ImgBurn to create a protected ISO Remove physical disc Enable AnyDVD HD Mount protected ISO with Virtual CloneDrive Use AnyDVD to create a decrypted ISO Unmount and delete protected ISO Disable AnyDVD Mount decrypted ISO with Virtual CloneDrive Use MakeMKV to create the MKV file, and put MKV file in Plex Unmount decrypted ISO and archive it This process has been working fine. But then I encountered Lord of the Rings - Fellowship of the Ring Extended Edition, Disc 2. When I attempt to mount the protected ISO for this disc (step 6), AnyDVD complains with the following error: Summary for drive F: (AnyDVD HD 18.104.22.168, BDPHash.bin 20-03-11) ELBY CLONEDRIVE 1.4 Drive (Hardware) Region: 1 Current profile: BD-R Media is a Blu-ray disc.

UHD Blu-ray disc. couldn't retrieve AGID! Cannot process request at this moment, please try again later! ERROR processing Blu-ray disc! The drive is Virtual CloneDrive, so the problem must be with the disc? Any thoughts on the problem here? Thanks!
