Allow users create video channels and add videos through wordpress

I am using a video wordpress script and would like registered users to create their own video channels and secure their own base url like [login to view URL] Channel creator will be able to upload / link to existing videos from vimeo or youtube, insert description, and set video image. perhaps we can auto detect image from url or embed script instantly like video thumbnails plugin. Also allow channel creator to delete or edit videos from his profile? When I try to create a new user through the website it redirects me back to homepage and does not work. 1. fix user registration not following through or proceeding through with script. 2. allow users to create their own channel ex. - [login to view URL] - Channel Description, set Channel Image. 3. allow only creator of channel to upload their videos by inserting youtube/vimeo video link - Title, Description, Video Image? (Perhaps Use Video Thumbnails) to detect image from video link. 4. Allow user to delete channel or videos from profile page?
