Fora.tv

I stumbled upon a site that I could recommend any teacher seeking for some complement for their lecturs. It holds video clips, both short edits as well as full length and covers 1) economy, 2) environment, 3) politics, 4) science, 5) technology and 6) culture. Every video contains metainfo, and a possibility to download it for listening/watching on a mobile device. You are able to create an account in order to make a playlist.

It definitly is worth taking a look:  http://fora.tv/
