If you want a great place to host videos that the members here can upload to themselves, I've been using Vidiac for some time on our local boards. It's completely free and you can set it up however you want with your own sections and what not. Moderators can also choose to approve videos before they are viewable which is nice in case some questionable material gets uploaded. It's the same setup as Streetfire. Take a look and see what you think.

Here's the one we use on our local board so you can get an idea of how it looks personalized to your own needs.

When you set up your sections, you just enter a list of keywords. Users are asked to enter some keywords when they upload and it will sort the videos out all on it's own to the most appropriate section. Really a nice feature to keep the workload off of the staff.
