Appendix B. Troubleshooting
Computer problems can be caused by hardware, software, or user error. The information in this section
might be useful to help you solve problems or to gather helpful information you can pass on to a service
technician. You might also need to refer to your computer, operating-system, or sound-adapter
publications.
Review the following list for any problem descriptions that might fit your situation.
You cannot create a multi-session disc.
Be sure that there is enough space left on the disc for another session. Writing a session requires lead-in
and lead-out space (about 15 MB) in addition to the data that is recorded.
You cannot successfully write to a CD-R, CD-RW, DVD-R, DVD-RW, or DVD-RAM disc.
Complete these steps:
1. Verify that the process is not being interrupted by a screen saver, an antivirus program, an Internet or
e-mail program, or other software. Disable the functions that might interrupt the write operation.
2. Verify that the hard disk has been defragmented.
3. Consult the hard disk drive manufacturer or vendor if an older hard disk drive is conducting a
thermal recalibration during a write operation.
4. Replace the CD if it is bad or scratched.
5. Disable the Windows Auto Insert Notify function on your CD-ROM and CD-RW drives.
You cannot eject a CD or DVD disc .
Complete these steps after ensuring that the drive is not in the process of writing to a disc:
1. Eject the CD through software.
2. Use the Eject button.
3. Turn off the computer. Wait 45 seconds; then turn on the computer and try using the Eject button
again.
4. If other methods do not work, use the manual-eject hole. Refer to the instructions in “Manually
ejecting a disc” on page 6.
You cannot read from the CD or DVD disc after successfully writing to it .
Complete these steps:
1. If you can read the CD or DVD Disc in another CD or DVD player or you can see previous sessions,
the directory information might be damaged on the volume, making it unreadable. To get ideas for
troubleshooting, check the documentation that comes with the software.
2. You might have a damaged CD-R, CD-RW, DVD-R, DVD-RW, or DVD-RAM disc. Try a new disc or
another brand of CD or DVD disc.
3. If you can read from a CD-RW, DVD-RW, or DVD-RAM disc in the writing drive, but not in another
CD drive, be sure that a UDF Reader program is installed in the computer.
4. Avoid writing at the slower 1X speed unless required by your computer.
You suspended your system and DVD playback will not resume.
This is normal with some device drivers. Playback will continue after you exit and restart WinDVD.
Unable to Create Overlay Window message appears when you use WinDVD with Windows 2000.
