First, the caveats:
There is no menu and no skipping, though fast forward and rewind work (usually).
Depending on your media and your player, it may not work at all.
The files will play in an endless loop.
You need to keep track of how much you're trying to fit on your media.
The files in each "set" need to be the same audio codec, i.e., DTS-MA or TrueHD, but not both (or anything else) in that "set."
That said, you need mediainfo to determine the codec (http://sourceforge.net/projects/mediainfo/
) and tsMuxeR (http://www.videohelp.com/tools/tsMuxeR
) to combine the files.
Select an m2ts file (one of Jindrak's, perhaps
), and determine the codec:
Monsters U. is True-HD, most of the others are DTS-MA.
Start tsMuxeR and "Add" a file.
(do NOT "Add") additional files as desired.
Select the Blu-ray output appropriate to your needs ("folder" actually creates two, the BDMV and the CERTIFICATE).
If desired, burn the iso or folders to disc with imgburn (http://www.imgburn.com/
With my HTPC, I have had no luck playing DVD-RWs, though the folders play perfectly. I'm assuming it has to do with the slow playback speed. Or it may be that I don't often use imgburn.
A BD-RE worked fine.
I don't have a dedicated BDP to try, so let me know if/how this works for you.
