How do you work this video website ?

That’s a forum. It’s a list of topics and boards. Browse down to the Online Videos section (it’s the second section down) and you’ll see a list of sub forums: Creative, New movies, etc. Click on the category you want, and you’ll see a list of movies/tv shows/whatever.

From the few I looked at, they seem to be links to other places to get or view the media and they don’t host the file themselves. I found none that I could download directly to my hard drive, nor would I trust a website like this over Bittorrent.
