Query: Multiple copies of this CD were defective!!!

MI ordered it twice, once from amazon marketplace, and then from Amazon, and both times, they were sealed copies. But when I opened the CD, BOTH volumes (it's a 2 CD set) were covered in a nasty white film on the readable sides of the CD, and were unplayable. I was shocked after I sent back the first copy, and then got a copy from good old reliable Amazon and found that copy defective too. Is this some sort of issue with the manufacturer???
