Query: Useful product for teaching kids

I did a lot of research on what to give my nephew as a gift. Finally I found this planet earth and was amazed about the reviews. so I went ahead and bought it. It was truly a good product. It helped to keep my 2 year old nephew quiet at least for a short period of time. Kids like to see animals and birds. It improves their understanding of nature.The camera work and the narration are extremely good. I haven't yet completely watched the entire series but I liked the portion that I watched. I am sure that this will be better in a Blue ray... Please buy it for your kids and yourself too. It is lot of knowledge.
