Hi Tony, I think you'll agree that most labels are now placing copy protection on their Cd's and understand why. But I too use my PC as an entertainment system and expect Cd's to play with good quality sound. Tesco's, Asda's will replace/refund money on any Music CD that will not play on a PC because of copy protection, even though you have obviously opened and used same.
I would take the CD back and ask for a refund if the quality of play is as poor as you say. Regards. j.
