OK xD first of all, go to this link

http://www.tektek.org/profiles/multimedia

and search for the video you want on your profile. When you find the right one, click on the link below the video, and copy it. then go back to http://www.gaiaonline.com, and edit your profile. When the toolbar comes up, click on content, then media, and a box should come up onto your profile saying media. click on edit on the media box, and paste the link from tektek.org into the box. then save and view your profile xD You can do this as many times as you like. Hope this helps!
