I'm using MakeMKV to rip a few TV show Blu-Ray DVDs that are directly from the shop. Ripping normal DVDs is just fine, but the Blu-Ray doesn't seem to work. It just says, "The volume key is unknown for this disc - video can't be decrypted." I read a few other topics on this problem, but the fixes didn't seem to work, or they were for older versions of MakeMKV.
I'm using it on a Mac OS X 10.8 and here's is a screenshot of what I end up with:

Am I doing something wrong, missing a step, or is there some way to fix this? Any help would be appreciated, thanks!
