HENRY2KOOL: Yes, I'm sure that I tested with 16x. I'm using CDDOCTOR 1.2.0 BETA PHASE 1 version, and it lets me choose between 8x, 16x and max speed... When I tested with max speed for those cdrs, the result was similar too. And also, I think from my box of khypermedia cdrs, they were all metal azo, cuz the color is all dark blue for them... Also just to let you know that, I burned one of those metal azo with OPTORITE CW5205 (52X24X52) CDRW, the result was very POOR. I got over 100 max C1 errors, and even some C2 errors at the end with max speed testing... so I think that cdrw drive might influence the quality... If you have another cdrw, can you burn/test with it, and post the results?
Oh, I also have a mitsubishi super azo, it was verbatim datalifeplus from my liteon retail package... I will post up the result for that one after I burn it.
