I've also had excellent results with memorex cdr media. I'd like to paste something I read from

CD-R technology is still evolving, as evidenced by the lack of a public ISO standard. The proprietary Orange Book Part II specifies format, physical, mechanical, dimensional, and optical specifications. It does not specify the method required to manufacture CD-R discs, and the industry is split between stabilized cyanine and phthalocyanine dyes. Each requires different laser beam powers and write strategies for optimum results. Since a standard for writers does not exist, model "A" might work well with certain brands and poorly with others. Results from model "B" might be opposite to those of "A". Throughput requirements complicate matters as higher speed writers become popular.
What media works best for my CD writer might not neccesarily be true for someone elses.
