Hi all I ve got a pioneer plasma 435 and a surround system dv990 which doesn t have component out and progressive scan. So i ve considered buying a good dvd player with hdmi out for my plasma but they are too expensive. Is hdmi soooo much better than component to deserve so much money? Anyway now i m between 2 dvd players with component out and dual progressive scan. The dv470 and dv575. The differences between them is that 575 has 5.1 out and plays dvd audio. I m going to connect it to my dv990 system which already has a 5.1 decoder. Do i need the 5.1 out? If not, how should i connect the dv470 to my home theater system? via optical output? Forgive me if this question is dummy but i m a little newbie.
