I need a new DVD player to use with my projector TW200 (the dvd from my all in one system keeps freezing). I am planning to use the RGB lead for it and feed the sound into the dvd/amp through optical in. My budget is £250. What do you recommend? I would like to play dvix as well. Is there really a big picture quality difference bewteen a £100 dvd player and a £250 player?
