Perian

Perian is like a magical fairy that helps your computer play different kinds of videos and music without any trouble. So, when you have a video or a song on your computer that your regular music player or video player cannot understand, Perian will come and make everything right. It's like having a special friend who can talk and understand different languages. Just like that, Perian can understand different types of video and music files and help your computer play them easily.
