 New subtitle stream 0:27 at pos:8284174 and DTS:20.0200s

+I mapped (i.e. selected to be inserted into the output) the **video track**, then **two adio tracks** (there were four), and finally **24 text subtitles tracks** (they are actually bitmaps in dvdsub format). The order of the **%%-map%%** options is used to re-arrange the position of the subtitles, overriding the autodetect performed by ''ffmpeg''. All the **%%-metadata%%** are used to properly tag the subtitles once they are sorted as I want.
 It is mandatory to use the **%%-codec:s 'dvdsub'%%** for subtitles, if you use the **copy** option (which does not re-encode the stream) the **palette** is not applied and you will get subtitles with wrong colors.
-Yes, the source is from an old tape camera, with annoying **interlacing artifacts**. So I used the **yadif** video filter to apply a deinterlace effect.
