Using tsMuxer, and provided the video stream is compliant (1280 x 720, or 1920 x 1080) it is a relatively easy process to remux the streams into a blu-ray folder.

Thanks!

Although after testing the program, I'm currently getting an error message when I try to import an mkv file. I did some research on this and its a common problem. I just deleted the two Korean fonts as instructed but that didnt work, so now I'm going to try to clear the font cache and see if that does it.
