As implied earlier, some of the sites may or may not be safe. Copying the URL will not actully get you the video in video format on your computer only a quick link to the video. Pasting the URL in one of the online converter sites will allow you to download the video, but I have had at least 3 occasion where I have had some serious alerts take place. Killing them can be a scary and involved issue for the novice. The program I am using seems to work well without security issues. Make sure you have your computer backed up just in case with the online sites.
