I recently ordered the Peyton Place series. Since I had already seen the first season and part of the second one, about the first 160 episodes, I put in disc 11 to pick up where I had left off. Disc 11 would not play. I checked all the discs, every third disk will not play (discs 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38 and 41). I contacted Classic DVD World and within just a few days they sent me replacement discs, they also said they would refund $15 to my bank account for my trouble. You can't ask for more than that. Everybody's human, we all make mistakes but they made it right!
