NU16 is set to run a Registry cleanup every Monday Morning.
After this task has been performed my DVD Rom drive is no longer available.
In device manager it states that the registry entries for the Driver are corrupted, (error 19).
This happens every time.
The only way this can be fixed is to manually go into Registry editor and delete the upper and lower filters for the device.
Please fix this BUG.
The applications that slot into the upper and lower filters are Slysoft's AnyDVD and Virtual Clone Drive (as this machine is running as a Video Jukebox).
I spoke to slysoft, who stated that if Norton didn't mess up the registry, then everything would work fine. The suggested I uninstall NU ;-)
So please fix this.
