The subject says it all. How much of a difference would I notice on my Sony WEGA KV-32FV27 while using a progressive scan DVD player? Would it accept a progressive signal through the component inputs? Would there still be an improvement in the picture quality to warrant upgrading? I currently have a Pioneer DV-525. BTW, the player I'm considering purchasing (after my audio system) is the Toshiba SD5700 Progressive Scan DVD player.
