I did see that program when it came out but as you say, it has been quite a while.  As luck would have it it is being shown again tonight, so I will DVR it and go through it so I can do a proper response to your post.  The show in your link was a James Cameron project to some degree and the narrator was the guy who went on to do the Naked Archaeologist series.
