I've been using MakeMKV (registered) for quite a long time without problems. I have a new DVD that I'm trying to backup without success. Disc plays fine on computer and Bluray/DVD player. My computer's working directory has almost 4TB available and system has ample power and RAM. Any and all help is appreciated.

Failed to open disc

are you able to make an ISO backup (possible with newest version) with the disc or would that fail as well?

In the newest version you can select between different methods to open the DVD. does changing the option help anything? See viewtopic.php?f=7&t=28541
