I'll take this -- do we want to simply include all of these on both of the areas? I've already added them under the videos section, however I wasn't sure where to draw the line in terms of going into one or the other. Maybe both is the correct answer?

Let me know and I'll go ahead and update the Videos section as well (if we decide to go that route).
