If a region code warning appears when you try to use your DVD-ROM drive,

connected.
If you are using multiple i.LINK devices, the combination of the connected

the connections for each device, then restart your notebook.

If the message “There are no Digital Video devices connected to this 
computer, or the power is off” appears, unplug the i.LINK cable and try 
plugging it in again.
