same problem here. I have stock subtitle files in the video file folders that work with all my devices (tv, tablet, iPhone, pc, laptop, ps3) for years now. I'm using a upnp server. Even changed a sub from 'movietitle'.srt to 'movietitle'.en_US.srt to see if that's was wrong but still nothing. Even if I go and select it manually it doesn't work. Gor any pointers for me? Thank u in advance.
