Question about Planet Earth

I have a little problem with the show. The fact that everything is "so rare" or "rarely caught on camera". When really I have seen almost all of it on other shows. One in particular really bothers me. The snow leopards. They said it was the first time a snow leopard had ever been filmed while hunting. Funny, I watched a Nature about snow leopards in the Himalayas over a year ago with footage of them hunting. What's the deal? How can they say that?
