Re: SVideo works fine, Component gives no video at all
Put the TVStandard definition in the device section for your TV. I admit this probably won't make a difference but it's how I had my system configured.
It's not the same anymore, but when I was doing this, I had much the same set up - a geforce6 with a DFP and the TV doing 480i over component.
Now, here's a question for you. Your card is reported as a 6200. Are you sure your card can actually do component out? It can't be assumed with a 6200...
You should also try turning off the DFP head to simplify your configuration for testing.
