I've had three Sony's, a Blau Monterrey, a sony changer, and a blau changer. Not one of them had a problem playing CD-R of any type, color, speed, etc. I realize that I am probably lucky, but I know people who have owned clarion, pioneer, alpine and eclipse that had varying degrees of success with CD-R. My advice is you try the different types of media and figure out what kind of CD-R works best with your HU.
