I bought this collection for my wife, and it seemed great. However, when she got to the 3rd disc of the 4th season, it was unwatchable! The disc would constantly skip, stutter, freeze, and jump back to the menu. I've tried it in two different DVD players and both have had the same problem. The disc has no visible scratches and is dust-free.

She hasn't watched the 5th or 6th seasons yet, but I'm worried that we might have another bad disc somewhere.

If you buy this anywhere, make sure that you can return it if you have a problem!
