I've been amazed by your cool videos. I had never seen a robot dog harassing an iguana before, or a monkey doing karate, and I had no idea you were such good dancers. There's more than home video, too - like this UNICEF story featuring David Beckham.
The clips play right in the page using the brand new Google Video Viewer, which was created by our engineer Aaron Lee using code from the open source Videolan project. It works great in both Firefox and IE, and we've designed it not to fight with any other video plugins you might have. We're releasing the Windows version first, with Mac coming soon.
A feature we're especially pleased with is search within a video, which means you will get a result pointing to the precise spot in the video that matches your query. Try looking for sergey brin and you'll see what I mean. There are even more people getting creative with video here. So have fun watching, or shoot your own videos - and keep sending them in!
