Ok, on the box it claims there are "OVER" 8 hours of original bonus content. I just purchased this set last week and watched the entire bonus CD tonight (disc 7). I didn't pay very close attention to how long it lasted, but it must not have been any longer than about 3 hours.

So where are the other 5 hours of content? They can't possibly be counting commentaries tied to specific episodes on the other discs can they?
