title: YouTube API: videoEntry context in playlist
body: <p>Is it possible to find the context of a video in respect to any playlist that it is included in? I would like to be able to check if the videoEntry is included in a playlist and, if so, figure out the next video in the playlist.</p>
  
  <p>Flickr has a lot of great photo context methods, I hope YouTube does too, I just can't find anything on it.</p>
