I don't think TMT is giving out any codec that can be used by 3rd party. They just offer an alternative to PowerDVD to play BR discs. (the reason I tell you that is that I also downloaded it and tried it).
In fact you can see a bunch of .ax files in their installation folders but these .ax cannot be registered with the system, and I couln't find one that would look like it's a video decoder.
