I am no expert, but i think your problem is the keystone, for an anamorphic lens set up you should never have keystone adjusment, you should try to make the image and screen as square as possible, to avoid geometry issues.

I wonder if the OP has had a chance to try the suggestions ppl have made in this thread. I would be interested in hearing the results/resolution. It's nice to get follow up feedback with threads like this, so if others have a similar issue, they are use the positive results as a guide for their own set up.

Per my suggestion above some prism lenses including the 850 introduce a horizontal image shift per Prismasonic. "NOTE: H-850M introduces some horizontal offsetto the image. The offset is to the left for table mounted, and to the right for ceiling mounted lens. This must be compensated by horizontally shifting the screen in respect to the projector, or if available, using the horizontal lens shift of projector." Therefore when using this lenses the projector is not dead center to the screen.

Sorry Glen I can't help with the UH480 horizontal shift or not...FWIW my Isco II doesn't but that isn't much help I guess.
What does amaze me though is that Jamie's threads seem to last longer than his interest in them.I've replied to previous threads started by him and then seen him start another thread asking basically the same question again. There is no 'thanks' button on AVS unlike AVForums so unless someone posts a brief reply you're never really sure if they saw your reply or not...kind of makes me less inclined to reply in future when that happens.
