I had the same problem with my kenwood dvd/stereo, will not play cdr/w, was advised to change media, i tried disks with a light blue writing side, copied a vcd workd ok.
dont get the dark blue sided ones as i tried them as well will not play keep getting error message, arita cds are good if you can get them i would try svp communications they have some.
hope this helps
