When I used Premiere 6 demo, I did not have this problem. But I did not use background picture in Poser5. I just used background color in P5. I dont know whether it is relevant or not. The picture aspect ratio was not correct. The pixel aspect ratio was automatically set to the aspect ratio of the file which was square. Movie uses landscape aspect ratio. I used portrait aspect ratio. I dont know if they can deal with it or not.
