This information does not apply to non-YouTube videos posted on the blog.
You may notice some subtle changes in the control icons shown on the bottom line of the YouTube videos used in our blog. The YouTube icon that displays numbers (360/480/and higher) shows the sharpness values of the different versions of a video. Use the highest number available that your Internet connection will play suitably. The square shaped icon with arrows at each corner are to enlarge the size of the video. If it will enlarge it will do so when you click. Some will, but some won't. You can right click on that same icon and go to the YouTube site to watch the video there. It may expand there when it wouldn't on the blog.
The YouTube video posted on 1/20/2010 with the waves crashing into the light houses is one that won't enlarge for me. But it is worth going to the Google web site version. It is spectacular in full screen and highest image quality. Be sure and check it out.
One more thing, click on the X to minimize ads in a video.
