So you can download some .sub .srt subtitle file from NET and watch movie on DreamBox/dbox2 with desired subtitle.
There is something on net for Windows DVB Subtitler v1.08 at http://zuggy.wz.cz/dvb.php
I think that this plugin is nothing more complex to do as Videotext, so I just waiting for subtitler release soon
Here is also direct link to saource code http://zuggy.wz.cz/download/source_1.04.rar
