If your set has RGBHV inputs then use the breakout cable, connect all 5 connectors, and you will probably have to set your DTV input to RGB (as I do on my Mits).
If it does not have RGBHV, only YPrPb, then use either the adapter cable that comes with the AIW or purchase a VGA to component transcoder.
