Where to find video clips for mp3 players?

I bought my son a Coby mp3 player for his birthday. It says that the player plays movies and video clips,but where can I find some to download? He loves WWE wrestling,and would like to have clips of his favorite wrestlers on his mp3 player. I just don’t know where to find ones that are available for download. Youtube is a wonderful video site, but it appears that you can’t download from them. Anybody have some suggestions?
