Have you tried its various 'Audio' options, or the Media/Codec info
under 'Tools'?

AIUI it's a container, now rare outside myth and little-used/obsolescent
within myth.
The audio bit-rate report looks as if mythffmpeg doesn't understand
something. Do you still have the original file? If so I would aim to
start again with a different kind of output. Replace the new file with
the old one, then mythcommflag --rebuild and go on from there. That may
work even if the original was .mpg and the new one has the .nuv
extension, but I can't be sure.
Or maybe someone else will have a suggestion...
