I just confirmed that Samsung’s TV software is defective; It does not support external subtitles when its streaming movies from a DLNA server.
1) Put a movie.avi and movie.srt in some folder at your DLNA server
2) Try to watch it with subtitles.
No subtitles will appear.. I just confirmed it with Samsung helpdesk. What a shame!
However, the external subtitles ARE supported if you bother to put the movie.avi and movie.srt to a flash disk, walk up to the tv and insert the flash disk. Btw, the TV does not support external hard drives either!
If you want to copy an entire disk’s worth of stuff onto another disk, here is the best set of parameters to do so:
rsync -avxI --owner --progress --group --links --inplace --stats --times --delete --modify-window=1 --size-only
