I own a Window'sXP computer. I'm still trying to learn how to use my burner that came with the computer. I have corrected the speed to the proper timing . I hit the "burn" tab to start the process ,I'm informed to install a new disc. I have placed a new disc in the tray,but still get the same request! The data is already to go.The songs are installed in the computer . My burn list is ready.What am I missing from this problem that occurs?
