you can change the screen size in premiere, this is the way: When u go to new project, the window comes where u type the projects name and destination, ok, go to the custom settings tab on the top, it says the screen size, but its in gray so u can't change it, it will say on the top DV Playback, click that to drop down the menu, and then click on Video for Windows, and then you can change the size. I hope that helps!!!
