The only way I know to do this would be to get the WMI Win32_CDROMDrive instances on the machine, then check for DVD in the Name or DeviceId properties.
You may even have to go so far as to get the DeviceID from the isntance then check in the Registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum[DeviceIdHere]\Device Parameters, then check for the existance of a value named “DefaultDvdRegion”. This won’t exist for CDROM drives, but does for DVD drives.
