a) Feel free to post your issue here, completely.
b) Screenshots are not useful at all. Who wants to type each of your
   arguments character for character to copy them, or to point out the
   error? Copy the text from the terminal to your mail (or forum post).

Sorry for the rant. ;-)

c) Now to the problem:

Newer ffmpeg now recognizes input stream 0:3 (as "timed_id3"), and
therefore no longer completely ignores it. But ffmpeg doesn't know how
to mux it into MKV, and therefore errors out.

You should tell ffmpeg to ignore it, by mapping only the relevant known
  -map 0:0 -map 0:1
  (map streams 0 and 1)
  -map 0:v -map 0:a
  (map the first video and audio streams, respectively)
or even
  (disable data streams).

(May I guess? Bør jeg gjette? NRK TV? Dette gjør jeg nesten hver dag.
:-) )

P.S.: "-dn" appears not to be documented very well. I will open a ticket.
