Randolph, You can't download a YT video in the movie maker, you have to download the video with a youtube video download program, such as
http://www.dvdvideosoft.com/ You can highlight the video address in the explorer address bar and past it into this software after it is installed. you can save the video or just the audio (I get a lot of music this way from youtube video's). Then you can load the saved video from your computer into the windows media player or movie maker and play it at 50% speed, (slo mo). That might help. I'm glad you are expanding your speed bag horizons. Alan
