Thanks for the reply. Never really tried my hand at re-muxing. So I’ll have to read up on that. For what it’s worth these same files work fine with captions in the plex web app and just playing on vlc locally. I’ll give the plex preview a try. It looks like the only update since the version I have now was released yesterday (Plex for Roku - #307 by ljunkie), and don’t really see anything specifically related to handling captions. But worth a shot.
