I set the speed to low setting and when I put the cd in my car stereo, it still says error. I am using a HP laptop with vista. I am using Sony CD-R blank disc. The disc burns fine then finalizes and ejects. I must be missing something here. Should I use a different disc? If so what brand do you suggest? I was using windows media player to burn and then I downloaded express burn, both with the same results. Very frustrated, I appreciate your feedback.
