This is already implemented. Only thing missing is selection of the 
pagenumber (now hardcoded to 888 = BBC standard), color support and some 
small bugfixes. All subtitle text is stored in the file, turning on/off and 
selecting only happens during playback.

Unfortunately I don't have the time to finish it all right now, so feel 
free to hack along... Small fix just by yourself could be to hardcode a 
different pagenumber, but as they vary in Denmark that doesn't seem usefull.
