I've just set up a DLNA server and tested my fetch mini - everything works fine. I am able to turn subtitles on and off. My question is - on a video file with multiple subtitles, how do I select specific subtitles? On/Off just seems to turn the first one on the list on and off. I've tried mashing the remote buttons but no combination seems to change the subtitles.
This sort of thing (playing from a DLNA server) is beyond the scope of this forum and would be best directed to Fetch themselves who develop the apps to play media that isn't from the Optus servers.
