I've used TDK, Verbatim & now these Memorex CD-R's, and I've never had a problem with any of them.
I'm not in the least bit "techy", but would suggest that the previous problems that others have posted are more to do with their systems, rather than the CD-R's that they're using.
My tower was built mainly from 2nd hand parts, has a dual-core processor, 500 Gb memory and a new memory board. Beyond that, I haven't got a clue. Perhaps a better informed and educated individual could confirm my suspicions ?
I received excellent service from indigostarfish, and would highly recommend them to others.
One final point; why would a global brand, like Memorex, manufacture a product that wasn't "fit for purpose" ?
Even if they are "out-sourcing", which I suspect they are, they must have QC in place to guarantee the quality of the product, surely ?
