title: What's the VOBsub subtitle format?
body: <p>Where can I find documentation/sample code of the VOBsub subtitles format? The one that's an .idx and a .sub file.</p>
  
  <p>I need to create a program that generates those subtitles. I've been looking on Google but only found how to rip them from DVD.</p>
  
  <p>Thanks</p>
