Hmmm come to think of it my HD satellite receiver also has DVI. Since I knew the Oppo has significant differences from its DVI and component connections I had to use the only HDMI port on my tv for it. I havent verified but I assumed my HD sat box would have similar video output via component or DVI. Not the case with the dvd player.
Now I'm gonna have to play around with my sat box to determine if I can notice any differences using the DVI vs component.
Also, I'd want to stress that there is little or NO major difference between using component or DVI/HDMI. Alan has run tests and feels the same way. I've read some articles and the only difference is to enable copy protection. I'm sure there are minor differences since component is analog while DVI/HDMI is digital but many people haven't found them. The Oppo is a unique case since the Foroudja video processing is only utilized with the DVI.
But to answer your question, it comes down to what you prefer, the cable box or dvd player. If your tv only has 1 input then its really up to you on how you want to wire it. I would recommend the cable box to component and
IF you get the Oppo definitely use the DVI connection.
Another alternative (which I'm also entertaining) is sell the old Denon and buy the new 3806/4806 to have HDMI switching. That damn upgraditus bug keeps nagging me
