Do anamorphic lenses on a 4:3 projector do anything for non-anamorphic ws content?

    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"?

    You should remove the lens for non-anamoprhic titles, it will just distort them. The resolution you will gain will offset any loss of light that's happening by going through another lens.

    An alternative to removing the lens for non-anamorphic material is to "anamorphosize" the image before sending it to the projector. Basically your display source pre-stretches the non-anamorphic image vertically before sending it to the display, so that it "looks like" an anamorphic source.

    This is easy to do with an HTPC, or an external video doubler/scaler. The Panasonic RP91 can also do this for DVD's.
