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...
