Do you mean COMPONENT outputs?  Composite video is one cable.  Component
out (HD, DVD) is 3 cables.  If you really meant COMPONENT, you need to
specify the TVStandard as HD480p, HD540p, HD720p, or HD1080i depending
on what the monitor can display.  Depending on the version of your
nVidia driver you may also need to specify TVOutFormat as COMPONENT.

To get DVI and TV out either let the card auto detect your devices or
change ConnectedMonitor to include DVI and TV.  You also may want to
enable twinview.  The nVidia readme has a section on dual monitor setups.
