Web Video Content Management System

I need some type of content management system that will allow me to input video files easily. Joomla isn't an option..it doesn't work for what we're trying to do. Take a look at these 2 sites, I'm needing the flexibility to do something similar: [login to view URL] [login to view URL] I'd like to be able to setup my own channels and add my own content. The video files should be able to archive itself when a new file is uploaded. Carl
