This led me to the source of the problem. The scene was about a cubic  
kilometer in size. I exported the whole scene including ground plane and  
universe. By going through everything and deselecting any unwanted stuff  
everything worked perfectly. It's a long time since I've done any poser  
stuff...

Thank you.
