If you want the viewer to be able to turn the subtitles on and off you probably won’t be able to do it with pure video alone. The reason subtitling works with dvd is that in addition to video and audio information of the dvd you have additional data (like subtitles) and an authoring environment that makes it interactive.
I beleive you would probably need to have the video file embedded into an authoring environment like Flash or Silverlight to be able to have user controllable subtitles with a video file.
