Do you watch the "extras" on the disc?

If I see a great movie on DVD, I will try to re watch most of it with the Directors commentary turned on. You learn a lot about film making doing this. For example, a few years ago, I watched Road to Perdition, a great movie, IMHO and the Directors commentary was excellent. In many of the shots the Director paid tribute to Conrad Hall, the famous cinematographer who died shortly after making this film.
