Could anybody possible advise me as to how to setup a link directory for video such as tv-links.co.uk?

They have it setup so that all of the links go to http://tv-links.co.uk/link.do/1/3377/5153/32604/49224 or some number like that. How do they go about doing this as all of the videos are hosted elsewhere? I would really like to make a clone of this site and need some help. Please advise!
