Oh, almost forgot. If you do manage to get your hands on an NJVC set, they are ISO files, which you should be able to mount as a virtual drive and also play without burning if you wish. It will do so with menus and everything.
For that, my experience on a PC is that Leawo Blu-ray Player works better. But Leawo is also free and the MAC OS version of it is here.
Have you figured out a way to make the menus work with Leawo? Apparently you can use the builtin virtual remote but I can never find it, so I usually just open the chapter menu and manually play the video file. Not all that concerned as I am planning to burn them to BD anyway but would be handy to have either way.
