After a few months of tweeking I finally got my Yamaha/Klipsch set up sounding good. I am now having issues with my rear projection tv hooked up to digital cable. My local cable company recently hooked up digital cable to my rear projection tv. They hooked it up(wife was at home, I was traveling) with RGB connections instead of the DVI. Outside of the fact that I cannot use several of the features, will the DVI cable make a big difference.
