KeepVid: Download and save any video from Youtube, Dailymotion, Metacafe, iFilm and more!

Just enter the URL for the video and it will save it to your PC.

I've used it before and it works well.

URL: YouTube - Motorcycle Hits Deer @ 85 mph, Helmet Cam 6-28-09

EDIT: Since it shows you the title, just right-click and hit properties and it will show you the YouTube URL.
