The tutorial on how digital video is put together is very comprehensive, going into such details as bit depth and compression, but they reference 0-255 bits as the video luminance range, which isn’t correct. For video, the luminance range is 16-234 bits, which allows for below black and above white. For computer video however, 0-255 is correct, but that’s not what’s on a DVD or Blu-ray (or what’s presented in broadcasts, for that matter).
Spend the extra money to go for the double-disc WOW Blu-ray version, as the eleven clips of various natural scenes are simply gorgeous to look at in breathtaking HD, made all the more enjoyable by the fact that you will have already adjusted your HDTV to look its very best.
