The mkvpropedit tool has a alternate method of referring to tracks.
Instead of the liner track number you can specify the type of track
(v=video, a=audio, s=subtitle) and then the index within that type.
Therefore track 's1' is the first subtitle track, which is just an
alternate name for track id 4. The nice thing about the 'tn' numbering
it that it has context to it. Track 's1' always refers to a subtitle
track, where is track '4' could refer to any type track.

For this file, track 's1' would be an alias for track 2.
