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.
