I'd say you have only one audio stream. -map is for selecting streams, like german stream next to english, next to french on DVDs, not for surround vs. stereo vs. mono. What you probably want is to re-encode this one stream to stereo or mono. -c:a copy won't do this, you need a real encoder. HTH, Markus -- - - - - - - - - - - - - - - - - - - - Dipl. Ing.
