Hi I am in the process of Building my HT, I would like to make a 100" screen with "screen goo", but I noticed yesterday when I was playing the extras on The Matrix Reloaded it swithced between widescreen and Full screen size?? If I make the screen 100" and I am viewing the Extras would the Full screen be OFF the screen?? Is there some adjustmemts I would have to make on the projector to compansate for the Full screen widesxcrren switching?? I would like to use the FULL "100" for the DVD movies and HDTV?? I will mainly be using the HT for Movies "DVD" and some HDTV.
