I've used TDK CDR's for years and never had a problem. I appreciate that other people have had problems and when I purchased my most recent batch of CDRs I considered buying another brand because of the number of negative comments. But I bought TDK again and have had no problems at all. I have no idea why manufacturing CDRs should be so tricky but it seems that a brand that works on one person's machine won't work on another. The usual advice is 'find what brand is best for you and stick with it'. As I say, TDK works for me. But it seems ridiculous that the whole business is so 'hit and miss'. You'd imagine that with today's technology it wouldn't be so hard to manufacture a CDR that works for everyone!
