Another alternative is to run the Oppo component outputs to the 990 and the DVI directly to a DVI input on the TV (that's how I have my system setup). So for everything except the DVD player, the 990 handles all switching and hands off a component signal to my flat panel. When I'm watching a DVD, I switch the panel over to it's DVI input (or HDMI as the case may be) to get the digital video while the 990 continues to handle the audio. If I'm feeling lazy or the kids are watching Sesame Street DVDs, I just leave the panel on the component input so I still get upscaled video over the component output of the DVD player. I don't think you have that option with the Oppo since it only upscales on the DVI output.

Cheers,
