One of my friend has a lot of videos on his website. I made a Video XML and submitted it to Webmaster tool. Also uploaded some videos to YouTube. YouTube videos work fine and comes up in ranking with YouTube URLs but I want to make sure that the videos comes from his site, not from youtube. Suggest me what all should I be doing to ensure that the videos comes from his sites under top SERP rankings.

Thanks,
Aji
