MelodyCan YouTubeRipper plug-in for Internet Explorer is an easy to use program to download video files from Youtube site. MelodyCan supports MP4 and AVI as output formats for video conversion. You can select a desired output format and video size in MelodyCan settings by choosing a suitable encoder for video files. Just click on "Rip YouTube File" button on your Internet Explorer toolbar and the selected video will be saved to your PC in a desired format.
I have never personally heard of this product but I wish I had, MelodyCan allows you to remove the DRM protection on many video and audio formats, which if you are a legal payee, you will probably need!
