Well, I havn't used Ppro in a while, but when you first open up Ppro, you have your project settings. Choose the Standard NTSC project and then hit the "preferences" or "advanced" tab, I'm not sure exactly what the button was labled, but it is the only one there. In the project settings tab you will then see the "lowerfield first" box, click on it to change it to "progressive". Hope this helps.
