Comment (by ramitbhalla):

 This is very incorrect:

 Guessed Channel Layout for  Input Stream #0.0 : stereo


 It should give this (like the TS file does):

     Stream #0:1[0x101](eng): Audio: mp3 ([3][0][0][0] / 0x0003), 0
 channels, s16p (hearing impaired)

 I don't understand why in the TS file it reports it correctly as 0
 channels while in the WTV file it "guesses" 2 channels.

 If this is correctly done, then I think it solves the problem of selecting
 the "wrong" default audio also. I remember reading in some documentation
 that ffmpeg chooses the audio track with the highest bit rate/channels etc
 - which is EXCELLENT, except this guessing has completely messed it up.

 3rd Party application depend heavily on the output of the "Stream #" line,
 so any mess up there will completely mess things up.
