Check out my new plugin that allows you to download Roku compatible subtitles from OpenSubtitles.org and convert any video in your libraries to MP4 which should Direct Play on just about any Plex client.

If you are having any issues with this plugin you will need to post your PlexTools error logs, otherwise I won't be able to provide much help.Thanks!
