Planet Earth

Has anyone been watching the HD Discovery Channel Planet Earth series? They are by far the best earth documentaries I've ever seen. There are 11 episodes and I didn't catch the first runs. I am now desperately trying to DVR whatever I can. They must have spent a ga-zillion dollars producing it, visiting 62 countries for filming. There are a few animals eating other animals scenes where I have to do a partial-eye watching from behind my hands and knees, but overall it is the most beautiful footage of our planet. Sigourney Weaver narrates the series in the US-run versions and there was a funny bit where a parasite was protruding out of an ant and she described it using an alien reference.
