Life's Greatest Miracle  
Watch The Program - Advanced Options
This hour-long program is divided into eight chapters. If you experience difficulty viewing, it may be due to high demand. We regret this, and suggest you try back at another time. Due to rights restrictions this program is not available for downloading. This program is rated TV-14,S. Viewer discretion is advised.

Listed below are individual links to the various QuickTime versions available for each chapter, including a full-screen (860x600) version not available from the regular Watch the Program page. When you select the QuickTime link for a chapter on the regular Watch the Program page, you are shown one of three 448x336 versions. Which one you see depends on the connection speed set in your QuickTime settings; the three versions are available individually below.

The full-screen version is created by playing the 76.0 Kbytes/sec 448x336 version at double the regular playback size; the additional processing power this doubling requires means that some older computers may not play the full-screen version smoothly. If you find this to be the case on your computer, try the 76.0 Kbytes/sec 448x336 version.
