I am probably not the best guy to try to help with this but
hopefully those that are will jump in.. please feel free to do so.
What IS the resolution of your original images? If PD is 'downsizing' them, can you either get a mediainfo or properties of the images after they were downsized?
I've imported many images into PD13 (what I'm currently using), and have not had an issue with resolution degradation.
I guess I'd ask you to make sure your outputted or final project is of the resolution that you want to view it at. Also, but I think you may know this, a Standard DVD has limits on what max resolution it will present itself at when viewed.
