hi this is going to sound a bit stupid, at the moment i have the cabling set up as follows: dvd to avr: composite video/optical cable avr to tv: composite video/analog rca i have no component or svideo ports on my tv and am restricted to composite/rca on the telly, until i get a new tv of course, but not just yet. my avr doesnt have a svideo port (that i can see at least) and the dvd has both svideo/component. would changing the composite/optical cables from dvd to avr to component cables improve anything taking into account the type of cables (composite/rca) used from avr to tv? im guessing not but im a bit new to this lark and like a few other opinions. thanks.
