I now have 4 pieces of gear that have component outputs: 1) Toshiba DVD player, 2) Comcast HD set top box, 3) XBOX w/ HD A/V Pack, and a newly acquired 4) Zenith HDV-420 OTA HD set top box. This leaves me one input short. My problem is that I only 2 component inputs on the back of my Sony DA4ES, and 2 components on the back of my Panny 53WX42. Since I have been considering an upgrade to the Yamaha HTR-5790, I was thinking that I could run the XBOX through the Yamaha's video upconversion thereby freeing up a component input on the back of the TV to make room for the Zenith set top box. Of course, I'll have to buy the non-HD A/V Pack for the XBOX. Considering that all of this works, will the game graphics take a major hit using the upconversion in the Yamaha? I consider all of this such a small sacrifice to shelling out $100 for a component switcher. Plus, I gain PL2x and YPAO w/ the new receiver. How does this sound?... I am open to other cost effective suggestions that some of you might have. Thanks in advance.
