While reading a recent post I was introduced to the DVI cable setup. I was wondering which is the absolute best as far as audio/video connections go. Is it RCA, the 3 color red yellow green deal, optical, s-video, dvi, or what? I am soooo confused. Right now I am using the optical for audio and the 3 color thing for my video. I do have a HD compatible TV. I am using a Denon 1804 receiver. I am also using a HDTV Comcast Cable converter box and a Denon 1815 DVD player. Somebody help!
