Here's the easiest proven method to capture those videos that RealPlayer Downloader no longer will download. First, download Youtube Downloader HD (yep, it's free). Run the program, set your default download sites, etc. Next go to the video you are having difficulty with and start to run it. As it's running right click on the video. One of your choices will be "copy video URL at current time". Click on that and paste it into the Video URL space in Youtube Downloader HD. Then on the lower right corner click on Download. Works every time.
