The highest C1 error rate comes from Mitsui media. The problem is that Mitsui CDs, have less recording capacity than other media. We burn data with 74:03:65mins long, so with Mitsui media, each drive must overburn, and as a result, in the last minutes the C1 error rate increases. With the rest media, writing quality is very good.
At the 32x writing speed, the produced CDs had also a good overall quality. However, the best results came from Taiyo Yuden 24x media, with or without the "JustSpeed" enabled.
