ViewPure: Useful tool for downloading YouTube videos without the extra comments, ads, suggestions, “related videos” or “inappropriate” other things that tag along with your YouTube videos. Use the website ViewPure by copying the URL of your chosen YouTube video and paste it into ViewPure where it will then strip away everything but the video. Some videos can be chosen at that time as well, such as dimension, background color. Or, a bookmarklet can be installed and clicked on anytime you’re viewing a YouTube video.

See my post on SnipSnip.it. back in February about a similar web tool.  SnipSnip.it
