The video shows you how to watch movies on your Nintendo DS. After a few required downloads, the video tells you how to encode your videos into .DPG. All you need to do after that is insert it on your removable SD. After doing so, running Sakura or Moon shell on your DS will allow you to pull up your files and watch them. If you follow the simple steps in the video, you'll be able to view your movies anywhere you have your DS with you.
