Some of my .MKV files (backed up from my own personal blu-ray collection of course

) have embedded subtitles. I know I can check the box to turn them on or off within the server settings, but is there anyway to turn them on or off during playback of a movie. Let's say in Lord of the Rings when they begin to speak "elvish", I want to turn them on, and then off when the scene is done. Thanks for the kick ass program BTW!
