If you only use one DVD player that has DVI outs, use this to connect to the DVI input of your plasma. Otheriwse, you may have to invest on a video selector box with DVI terminals. I believe newer receivers will sport this facility very soon, not just in their flagship models. Right now I still have to see a receiver with multiple analog 5.1 sources so I can switch between a dedicated DVD-A player and a dedicated SACD player - both requiring analog 5.1 inputs.
