Hi
Windows XP SP3
Have tried the proceedure below to fix DVD's not showing in My Computer and Code 39 in device manager.
Only found Lower Filters entry in registry which I deleted as suggested. On restarting the PC problem remains.
Can anyone suggest further course of action?

If updating the driver does not resolve the problem, it indicates that there is a problem in the registry. To fix this problem, you may have to remove a few keys from the registry.
After you have removed the registry keys listed below, you will have to reinstall all applications that you use for CD or DVD recording to make them work properly.
To fix the error by editing the registry, perform the following steps:
1. Exit and close all applications currently running on your PC.
2. On Start > Run type Regedit and press the Enter key.
3. Next, navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}
4. Delete any of the following registry entries if they exist under this key:
o LowerFilters
o LowerFilters.bak
o UpperFilters
o UpperFilters.bak
5. Restart your PC and open My Computer to ensure that the CD-ROM drive is visible.
6. Also, open the Device Manager again to ensure that the yellow exclamation mark and the error code is now gone.
