Comment (by pross):

 Just to extend what cehoyos said. The second audio stream contains no
 data. There are no reliable flags in the WTV file format that indicate
 when a stream contains no data.
 {{{
     Stream #0:2[0x32]: Audio: ac3, 0 channels, s16
 }}}

 This ticket should be recast as an suggested feature, i.e. give the user a
 warning when he/she attempts to manipulate a stream that is potentially
 empty.
