Thanks @Carl and @ Moritz for you hints. Stupid me!

The only thing I know to add is that the only text-based codec which seem to work for mp4-output is "mov_text". So this leads to a result:

=====================================

ffmpeg -y -fix_sub_duration -txt_format text -ss 0:03:24.23 -i /mnt/video2/Death_in_Paradise/_/2015-01-08.21.57.195-0.rec/00001.ts -t 00:59:05.010 -map 0:0 -vcodec copy -map 0:2 -acodec copy -map 0:4 -scodec mov_text /mnt/Data_bb/sda9/ProjectX/Death_in_Paradise_01_V02.mp4
