WHERE THE HEART LIES
With these Trophies you could do what I did and actually watch each video, which can take you anywhere up to 3 hours or more. There's that, or you can skip through them by entering the video, pressing O to back out and keep going down the list doing this. You can tell which ones you've watched when the background behind the title is blue so you can come back and continue if you have to go.
By the way, you can't just set the videos to "watch all" and then leave for a nap. There's certain instances when you need to click on the controller to continue after some text. So you need to be there in order to click X to continue.
