Windows Media Player cannot burn (copy) the selected files to
the CD. To fix the problem, do one or more of the following, and
then try again:
Verify that the CD burner (recorder) is connected
properly.
Clean the disc and verify that it is not damaged.
Try a different brand of blank discs.
If another program is currently burning files to the CD, wait
until the burning process is complete.
Quit other programs that might be using the CD burner.
Restart Windows Media Player.
Restart your computer.
Select a slower recording (write) speed for the CD burner.
Use the Windows Error-checking tool to check for file system
errors and bad sectors on your hard disk. For more information
about the Error-checking tool, see Windows Help.
To select a slower recording speed
On the Tools menu, click Options, and then click
the Devices tab.
In Devices, double-click the CD burner, and then click
the Recording tab.
In the write-speed list, select a slower speed.
If the problem persists, the burner might be malfunctioning. For
troubleshooting information, see the documentation that came with
the burner.
