component is great, it bypasses HDCP which is a right bitch to deal with. Also it can resolve some overscan issues with some displays...
The problem here is that they give you a "HDOut to Component" dongle that has nowhere to plug in on the card, since it has no HDOut plug. (HDOut LOOKS like an Svideo plug but has about 3 times as many pins, and it is not compatibly with svideo. It does however have a dongle that splits it into svideo and component video. ATI and nVidia have been using those for a while now, If I am not mistaken they each use a slightly different proprietary implementation)
