I got them fromAmazon.Sounds like you have some bootleg DVDs. I would report it to eBay and get your money back.
But I've had them for a few years now.
They play much better on one of my DVD players than the other one.
I have been watching them on a tiny TV in my bedroom.
I just hate moving the players around.
I figure it's just more chance for something to get damaged.
I even bought a new, really cheap player and tried that one!
It's just too expensive to try to replace them.
