I have the Panny TH-42PX25U/P plasma. Great TV. My DVD player isnt so hot...Sony DVP-NC875VS 5-Disc DVD Player. It seems that even with calibration the picture has more detail with Progressive on the DVD player turned off. When it's on the black obscures all the detail. Does my Panny do the deinterlacing on its own better than the Sony? Is Sony progressive that bad??? Thanks all!
