Oh sure, in 10476 it doesn't work well enough to even do that. :)

Ok, so I reverted to to 10258. I didn't think '+' should make a
difference, because as far as I can tell there is no audio stream being
recognized in the frontend.  Sure enough, '+' didn't do anything useful.

Here's the frontend log. The streams are still being parsed incorrectly
as video, and '+' only results in "AFD: Audio stream type not changed."

Other ideas?  thanks,
