There are GREAT differences in quality between different brands of blank CD's and DVD's, from more than 50% failure rate, to almost always good. Someone on this forum last year posted an excellent evaluation of the various choices, and I followed his advice with success. Now, however, I have run out of the "good stuff", can't remember the brand name, and can't find his post. It was very important, so if you are the one who posted it, please reply with the name of that "best quality brand." (the individual disks do not display a brand name, both a problem in finding them, and an advantage in making your products look more professional.)
