Video sharing site

What I am looking for is a video sharing site. Similar to Youtube as far as idea. Different in method. I would need a basic user sign-up and information page. Users will be able to put in basic info about themselves as well as add delete and edit their own videos. I will also need an Admin panel which lets the administrator delete, edit, approve, and add both users and videos. All info contained in the database would then output an XML. Please state "I understand" for consideration. Thanks!
