Some of you have written to me about problems watching youtube videos on this site. Sometimes, (it happens to me, too) the videos are very slow to download. It will pause while more data is being downloaded. This is very irritating, but happens frequently when many people are online at the same time. The red bar at the bottom of the video shows you how much of the video has been downloaded. If it seems to be moving very slowly, pause the video, open a new tab in your browser, and do something else while you wait for it to be finished. When the red bar goes all the way along the bottom of the video, you will be able to watch it without interruption.
Note that you need a recent version of Flash to watch the videos. If you have problems with the sound, check your computer’s audio settings, and/or the volume control on the Youtube video itself.
Good luck, and happy viewing!
