but the closed captions do not appear.
m To view a videotape with closed captions, you must connect
your VCR to a TV tuner port, not the video input card. If you
do not have a TV tuner card in your computer, you can
purchase one from an Apple-authorized dealer. Then follow
the instructions that come with the TV tuner card to see how
to view closed captions on videotape.
If your computer has a built-in monitor, the TV tuner port (if
you have one) is as shown in the computer on the left. If
your computer has a separate monitor, the TV tuner port is
as shown in the computer on the right.
If this port is present, then a TV tuner card is installed.
(The ports on your computer may look different.)
