Comment (by Selur):

 You are right and I was wrong (must have mistyped somewhere), specifying
 -map 0:0 does also help.

 My mistake was that I assumed that when no processing was explicitly
 defined for a stream type, the stream type would be ignored.

 But that is not the case.

 If the output is not a raw file, but a container like mkv/mp4/... ffmpeg
 tries to convert the first stream of each type to something that is
 compatible with the output container.

 Since I didn't specify -sn ffmpeg tried to convert the first pgs-subtitle
 stream to something which is mkv compatiple. Problem is ffmpeg can't
 handle pgs subtitles.

 -> So the problem was that I assumed something that was wrong (ffmpeg by
 default ignoring streams when nothing is specified for their type).

 Thanks.
