If you experience problems when decoding a 3DBD with BD3D2MK3D, such as black frames at the end of during the whole movie or infinite loops, please configure the MVC decoder to use SOFTWARE mode instead of hardware or automatic.
Select
Settings -> MVC Decoder -> Hardware Acceleration -> Software (use if Auto crashes)
And please report here if you have had that kind of problems, with what movie and if using the software mode has solved the problem.
(If you are interested, that problem has been reported for the first time
here.)
