Looks like there is a new Blu-ray player out, called BDBoom: http://ivscat.com/
I've seen a post at Videohelp.com, but no one there seems to know much about them. The software is not free, but there is a 30 day trial available. From a discussion at Vhelp, the player does not support Blu-ray menus.
This isn't just a player though. From the description, the software has decryption and ripping capability as well, since it can save files locally or make an ISO from the Blu-ray.
It is compatible for Mac and Windows, though the decryption and ripping options are for Windows only at the moment, soon to be extended to Macs.
