Hi, I have a Sharp XR-10S projector hooked up to an HD cable box. Right now I'm using S-video and digital optical connections from the cable box to a Sony STR-DG800 receiver then to the projector by S-video. The cable box has DVI out and the receiver has HDMI in (for cable boxes). If I get a DVI to HDMI cable, will this work? And will the image and sound be better? From receiver to projector I only have S-video and yellow video coaxial plugs available. Thank you.
