There will be some BR discs that give it problems. For full functionality, you should have recent Java installed, and appropriately pointed to for MakeMKV to find it. The issues are more likely associated with Blu-Ray.

The MakeMKV forum is a good place for exploring that, and possibly also here on VH. Yes, your particular hardware could be a factor. This is probably not in the class of a cut & dry, 'one-size-fits-all', 'set it and forget it' software there can be some wrinkles, if you are not diligent about looking into them. It has worked pretty reliably for me for the most part, with occasional issues on certain rigs. I've used it for years (on Win 7 圆4), prior to purchasing a license. Congratulations to the developers, and I hope there will be more evolutions of this program. I have not used makemkv for some time, but I do recommend using the program (I am aware of its existence and have used it in a variety of ways since the years of 2015), because it is simple in its proposal, which is to transform the entire structure of a bd or dvd (video audio tracks and subtitles), in a single mkv file, and for those who do not have a desktop player to watch their physical media, but have a media player, this program, it is more than mandatory, to facilitate the whole process A nice point to highlight would be the possibility of testing the program for a generous period, let's say, with a free key (since the price of the program itself may be of little accessibility but I understand why the value, in view, of its functionality and proposal), this allows the user to have an honest judgment of the program, before buying, if any kind of 'surprises' Anyway, in my opinion, it's an excellent program that got it right, in simplifying a process, at first simple, that can be done with other programs, but it would demand a lot of work and time.
