Strange problem. I am running WIN XP with a Lite-On 24X CDRW drive. I have had this computer and burner for exactly one year. During this period of time I have used more than a dozen brands of media with no problem. Recently I purchased 100 Sony Supremas 40X CRD's. My burner recognizes them as 16X only. I have tried 5 CDR's from this stack and the result is always the same. My friends computer using a Plextor 48X burner properly recognizes these CDR's as 40X.

What's going on? Is the problem in the CDR's or my burner? Has anyone else ever encountered a similar problem with a burner that fails to properly read burn speeds?

Thanks for your help.
