The Digital Photography Review is a web site that is oriented toward cameras which take photos: no big surprise given their name. They recently posted a Guide discussing video which explores DSLR cameras and their relatively recent addition of video recording.
The guide is titled "Beginner's guide to HD video" and it is also described as "Digital Cameras and Video: A Beginners Guide". If you are interested in this subject, see http://www.dpreview.com/learn/?/Guides/ ... ide_01.htm
