My wife started watching these the other day and just tried to put on Disc 3, but it won't play at all. No menus, no nothing... except "C13:00" flashes on my DVD players' menu screen. That is an error message on my machine. I have a Sony S-360 which has never had a problem playing any disc. Even the seamless branching features on discs like T2: Ultimate Edition won't phase it. And other discs still work fine, even the other Buffy discs. No scratches on the disc either; this was the first time that its been in the deck! I'm inclined to believe that I have a defective disc. Anyone else have a problem with Disc 3 of Buffy? Fortunately I still have my receipt so no worries there. What gives?
