I have solved my own problem this time. I burned from the finder and now I can read the disk with other computers. I thought I had the newest toast. I will have to make sure. I also read on the net that that superdrives are DVD-RW. My next test. Does anyone have any suggestions? Cheers Tony __________________________________________________ Do you Yahoo!? Yahoo!
