Is there a list of programs that do no "play nice" with Mezzmo? I have been testing open source video converter/transcoders, and Mezzmo has stopped transcoding and playing MKV (primarily) files.

I have uninstalled it, and reinstalled it. I have run the Mezzmo repair. I have upgraded to the newest version,and then down graded back to version 2.3.2.0 (which seems to work best for my setup). I have also uninstalled the programs I thought were the problem.

Last time this happened, I was ready to blast my HD anyway, so I just did that. A rather "heavy hammer" for such a small problem.
