I have a progressive DVD Player and Plasma TV and I'm using progressive output daily but I just realized I know nothing about progressive scan! I don't know how it works and there are some major plot holes in the scenario for me. What I have learned is that when an NTSC film is played by the DVD player, it adds the 3:2 pulldown. Now with a progressive player, it takes this signal and uses an "expensive" chip to reverse the pulldown. First, my question is why all the trouble for the progressive player? I know that NTSC movies are encoded as 23.97 fps on a DVD. Why the player doesn't get that directly? Doing that conversion twice is useless. Second, my big question is that no matter what, the result is 24p frames. So how that 24 frames are gone through the NTSC signal and shown on a TV? Because NTSC is 60hz!
