When I first heard this theory esopoused on this list, I had a
difficult time accepting it.  At the time, my only projection
experience was at the home of a self-taught friend...and we both
assumed that the horizontal should be adjusted.  After having the
opportunity to watch experienced projectionists at work, I quickly
became a believer!  No, George, you are not off base at all!  In
fact, I recently had the opportunity to observe both projection
methods in use on consecutive nights.  Minimalist is absolutely
the way to go!
