From HD YouTube Downloader:
Free Youtube Downloader HD is the best solution available for downloading youtube videos free, fast, and in HD. Youtube Downloader HD also converts file types of videos into .AVI and .MP4 so that most video players can read them. Simply find the youtube web URL of the Youtube Video you want to download, copy the link, paste it into the program and start your free youtube downloader. Within seconds it will grab and download your youtube video fast in the format of your choice (including .FLV and .MP4), and the quality of your choice as well (1040HD, 720HD, medium quality). Free Youtube Downloader HD can move from higher definition to lower definition videos so if the youtube download you want is only available in medium quality it will try to download in higher quality HD and move down until it finds the highest quality in which that particular youtube video is available. Finally Free Youtube Downloader HD has never and will never charge for our software. We believe that people should be able to download free youtube videos without having to pay extra for something that Youtube should have added to their site a long time ago.
