Query: Terrible set - bootlegged??

I've had to replace most of this set due to bad DVDs which are completely unwatchable - more than one too. I've replaced season 2 and now I'm going to replace season 3. It was too late to return the product. I would recommend buying the show in single DVDs. The only thing I can figure is that this set must be bootlegged.
