I have a Panny PT47wx42 and am looking towards getting a progressive scan DVD player. I understand that the old model locked into full mode when fed a progressive source making a scaling DVD player a recommended accessory. The new model, '42', allows for all scaling except 'just' (stretched) mode. I guess I'm not quite clear on this scaling need? Non-animorphic dvd's need to be scaled, yes? Do I still need a scaling DVD player? Could somebody explain this to me? Thanks a ton!
