Community Site with Videos

I would like to get a site where people will be able to show videos from different sources (you tube etc) mentioning the URL, and as an option uploading some videos. It would be a site where people could be part of a community, where registration, discussion forum are used If you have experience or have some ideas let me know some samples , maybe something like [login to view URL] (in spanish) or [login to view URL] would be perfect (here they upload videos) Budget suggested is around US$500
