The New York Times video page hosts a decent collection of news video clips. It can be accessed from NY Times homepage using the Video tab, or directly at http://video.on.nytimes.com/. There is a category listing, a search box, and a "Most Watched" feature to find and select videos.
It looks like there is some good content here relevant to typical English I research topics. Introducing a topic through video is a great attention grabber, and can be used to start a discussion about how one might go about further researching the issue presented in the video.
