@ damascus ; I know you've had a lot of suggestions but give these a try .One at a time.
To enable CD burning
1.From the Start menu, right-click My Computer, and then click Open.
2.In the Devices with Removable Storage area, right-click the CD drive, and then click Properties.
3.If your CD drive is recognized, you will see a Recording tab. On the Recording tab, verify that the Enable CD recording on this drive check box is selected.
To disable or limit IMAPI
1.Click Start, point to All Programs, point to Administrative Tools, and then click Services.
- Right-click IMAPI CD-Burning COM Service, and then click Properties.
3.Set the Startup type to manual.
On my XP OS this is set to Disable so try with manual & disable.
To reinstall the MS generic cdrom drivers.. In my computer, tools, folder
options, view tab, in advanced settings, you'll need to first mark "show
hidden files and folders", then uncheck the box for "Hide extensions of
known file types".. Now you can go to the windows\INF folder and find
"cdrom.inf" and right click it, select install from the menu.. Remember to
change back to your original settings in folder options.
Download the SPTD standalone installer from http://www.duplexsecure.com/en/downloads
Execute, choose uninstall & reboot.
If none of these help try:
Removing all Roxio & Sonic from your OS may help.
If all of the above fails:
Remove anything Nero ( that you can reinstall if you want or need to)
Reboot in between these .It's not always necessary but usually good practice.
I saw where you are anti reg cleaner so I won't suggest CCleaner.I use it & haven't had problems but I don't just check everything & let it go.
