(Though NB with CDs/DVDs you lose that right once you break any seal on the discs, to stop people sending stuff straight back once they've copied it.)
Rights on faulty goods last a lot longer than 7 days, even though you should always act as soon as you discover the fault, and you're in a better position the earlier you find and report it. If you first play the discs weeks after purchase, you may technically have lost your right to reject the goods and 'rescind the contract'. Rescission puts the parties back to where they were before the contract, so you get a full refund and they get the goods back. But the next remedy if you've lost your right to reject, compensatory damages for the fault you're stuck with, only makes sense on an opera set if the damages are 100% (because you've got to buy another complete set to get the missing disc). That's why if you're suitably firm you'll probably get a new set out of them. At least they then get the dodgy set back and may get a credit from their own supplier.
