Ah! Thanks.

I believe that Nut _is being _maintained, but it is not being improved, and it is not gaining new features. Granted this comes from Wikipedia and Google searches.

Okay. As that's the case, I'll hold off for now on switching to mkv, and do some testing with media containing AAC content.
I'd welcome whatever you find as regards to this, of course.
