I don't have the equipment myself, but I don't think you will be able to. The whole idea behind the DVI/HDMI connectors was to give the ability to transfer in digital without being able to record in digital. You are stuck with the analog recording.
By transfer, I meant viewing. It will take the signal from point A to a display point B. Unless you can find a hack for HDMI, you can't do much else with it.
