Not really experienced in this PS technology and would like to find out a few things. I have a Panny 6 plasma and a Pioneer 575 DVD player. As I understand the Panasonic will convert the signal to progressive scan as will the dvd player. But how can I stop the Panasonic from converting it so I can see if the player can convert it better - or am I being stupid. I am asuming that because I cannot tell a difference AT ALL when I switch PS on and off on the DVD player that it is the plasma that is doing the converting - is this right?
