If I transcode the original file with above command line without
-fix_sub_duration the subtitles in the resulting output file are
approximately 75 seconds late (making the subtitles unusable), with
-fix_sub_duration the subtitles in the output file look fine (tested with
mplayer and mplayer -ass).
Please note that I originally did not upload the ass file because I am not
convinced it allows to reproduce the original problem (see also my
original comment that includes a working command line after remuxing the
unchanged subtitle stream). I only uploaded it on your request.
