How to make a movie out of downloaded videos?

Question by Panda!: How to make a movie out of downloaded videos?
So my best friend’s birthday is coming up, and I’ve been trying to make her a movie out of her favorite videos from the internet. But after I’ve downloaded the videos from keepvid.com and tried to add them to Windows Movie Maker, it said that “file is unknown and cannot be added to this program”. Help! How do you make a movie from downloaded videos? 🙁

As to what format u need i have no idea.
