MakeMKV is primarily a tool for making mkvs from encrypted or unencrypted blu-ray and dvd content, whether on a commercial or home made disc or on a hard drive.
It does, however, have a full blu-ray disc back-up function (i.e. it can make full hard drive back-up copies of encrypted commercial blu-ray discs).
Further, while it remains in beta testing, which it has been for several years, it's free.
It's blu-ray back-up function is slower than commercial decrypters as it's maximum reading speed whilst decrypting seems to be limited to 1.6x. However, the limited reading speed seems to be an advantage when dealing with troublesome discs.
All of that said though,I suspect that CDan is correct and that you have a defective disc, even though it may not be so defective that it won't play on a stand-alone player.
