I have a 5 year old DVD player. It has the following connection in the back 2 RCA Style Outputs 1 S-video Output 1 Component Video Output 1 some sort of Digital output (I think) this last one is part of the question. The are two white RCA female ports and an unknown port between them (Kind of square looking). What is this series of ports and what would I send the signal to? Also my TV is and HDTV Ready TV the 47" Panny thats been discussed several times on these boards. I know the component video will be an improvement between my s-video hook up but would the picture benefit from a progressive scan DVD Player? Would it be a noticable difference?
