I was having trouble backing up a DVD I have and read about a workaround.
I was running AnyDVD and turned it off.
I then started DVD43.
Well the two do not play nicely together!!! Crashed my sytem and now my computer will not recognize my CDRW or my DVD Burner.

I have uninstalled DVD43 and ANYDVD and rebooted (several times).
I have uninstalled and reinstalled the drivers for both my CD and DVD (several times).
My computer seems to have the correct drivers onboard (validated by driver agent). Nothing I do seems to allow my 'puter to "see" my CD or DVD drives...

What do I do to fix this problem?

Are the drives listed in Device Manager?
Start > Control Panel > System > Hardware tab > Device Manager button

Have you tried booting into safe mode to see if they show up then?
Restart Windows after you see the BIOS screen and before Windows starts to load.
Start tapping the F8 key. The Windows Advanced Options Menu appears.
Use the Arrow key to ensure that the Safe Mode option is selected.
Press Enter. The computer then begins to start in Safe mode.

5. On the Edit menu, click Delete, and then click OK.
6. Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.
