A collection of DVD videos about Ferns, Flowers, Mosses, Pines, and leaves combining living plant stages with computer animated simulations bridging the gap between familiar plants and the micro environment. These DVDs are rated region code zero (PAL format), the TV format used in most of Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries (See the table of countries and standards at http://kropla.com/tv.htm). NTSC is the TV format used in Canada, Japan, Mexico, Philippines, Taiwan, United States, and other countries. Most NTSC TVs don't work with PAL video, but computers with DVD players will play either PAL or NTSC formats. (See System requirements for more information)
