Today I learned yet another new thing regarding front projectors... Lens use. I love the idea, since the projector that's keeping me up these days does not have a native 16x9 mode. However, I'm unclear as to whether or not an Isco/Panamorph/etc. lens will do anything for my letterboxed (but non-anamorphic) movies, such as Titanic, Pretty Woman, or my SW laserdiscs. Also, is there any drop in quality when projecting through a lens as opposed to using the 4:3 PJ "as is"?
