Ooops! nruddock is also right; all the P6 default files are compressed, and that mucks things up a bit too. There is a pyton script in the menu to uncompress all resources. You -may- be able to do this with DS as long as you export your scene as a pz3, and expect nothing more than P4 initial quality. How long you can do it is going to be a different matter, as file formats evolve...
