As a small caution to those who may be burning the MKV right to Blu-ray, be prepared to brick one blank in the event your player requires a Blu-ray spec file structure in order to recognize the file. The physical optical drive on some players might require a very rigid structure within spec to work.

I don't know if my own player would play an MKV directly from disc. My current setup is a small portable Seagate backup drive (1 TB), connected via USB to my Blu-ray player. That works flawlessly, but I am planning to purchase a BRD burner for this and other projects.

I know this might require a little (gasp!) research and (gasp!) work, but the BR file structure doesn't appear to be too complicated. It's not much different from AVCHD, which is why 2.1 worked so well with so many players. For example, there are free programs out there that will mux MKV to .m2ts (TSMuxer), which is used by BRD. That might be the first and most complicated step in making this work on physical disc without compression. Have fun people. Maybe take a shot at designing your own personal menus. I might try that myself and see what I can come up with:)

You can also use TSMuxer (cross plateforme tool) to turn the mkv into a Blu-ray (without the menus of course).
