I found that PS3 (and other players) now support XSUB streams for subtitles - see http://en.wikipedia.org/wiki/DivX#DivX_Subtitles_.28XSUB.29 It would be great to add support for on-the-fly XSUB addition from .srt or .idx/.sub files - probably via transcoding options. It basically means to create additional stream holding the subtitles…
