well, I have my first problem. And It's a big one. If I run 720p through the 4600, and then to the pj, i am getting waves all over the place. Vertical waves, scrolling horizontally. 1080 is fine, and 480i/p are fine
Changed cables, even plugged the projector into another circuit.
NH, can you test yours? It's more noticeable on dark or back colored scenes.
