If they replay what you saw we can help you identify what it was. My guess is it either the Legacy Revealed Documentary (http://www.history.com/shows/star-wars-the-legacy-revealed/videos/star-wars-the-legacy-revealed-discovering-star-wars#star-wars-the-legacy-revealed-discovering-star-wars)

or the Empire of Dreams doc. (http://en.wikipedia.org/wiki/Empire_of_Dreams) or a friend was showing you the fan made doc. Deleted Magic. (http://originaltrilogy.com/forum/topic.cfm/Star-Wars-Deleted-Magic/topic/1284/)

No it wasn't any documentary it was the movie with all the deleted scenes back in and remastered. They where even colored in.
