Audio and Video
To transmit video signals through the S-Video-out jack, you need
an S-Video cable, available from most electronics retailers. If you
are combining audio and video functions, such as playing a movie
from a DVD in an optional External MultiBay drive to a
television, you also need a standard audio cable, available from
most electronics retailers. Connect the audio cable to the external
device and to the audio line-out jack.
