I think i finally got the solution. How ever it seems på be a long way 
to go. I can't get it to work in one operation. I have been looking on 
alot of examples on the mailing list, ffmpeg wiki and stack exchange.

So now i found the way to get the one subtitle that i need, with this:

ffmpeg -txt_format text -txt_page 599 -ss 00:04:45 -i 'Beck_ _je for _je 
(4).ts' -to 00:05:00 -map 0:s:0 -c:s:2 mov_text -metadata:s:2 
language=dan 'Beck _je for _je (4).srt'
The -txt_page number i get by using VLC. So now i have the .srt file. 
Don't know how else to get ffmpeg to pick that one subtitle.
Then i encode my video as i always do.
Then i combine it with:
ffmpeg -i 'Beck _je for _je (4).mp4' -i 'Beck _je for _je (4).srt' -c:v 
copy -c:a copy -c:s mov_text 'test.mp4'
This seems to be working. But is a long way to go.
