I received my Blue Planet DVD set in a timely fashion. I received them in the package new and they were in mint condition. I was excited and popped them in my DVD player. Bad News... they're messed up. The DVDs skip around and worse yet, three of them don't read at all. I tried them in two different DVD players and they still don't read. I'm sure this is not the sellers doing, rather, the manufacturers problem. My problem with the seller is that I have sent two emails to them and still, no response. This is terrible service and a terrible product. I;m frustrated. BUYER BEWARE!
