okay, here is my dilemna. my ht system has been working great for some time now and i just purchased a new dvd player( never had one up until now). presently i have the audio stuff going through my a/v receiver but the video stuff does not go through the receiver at all. now, i see you can hook up the dvd player audio portion to the receiver either with an optical cable or a coax cable. Which is better?. the video signal im confused on. do i just take a cable with rca ends and connect one end to the dvd and the other end to my video in jack on the tv set. i'm confused on all these connections. i see that just a 3 wire cable with rca ends come with the dvd player but i don't think these will work the best. thanks for the help.
