What's behind the sheet? I was surprised before I got my screen that my theater's red walls were watchable. Not as good as the screen, but not that bad. It may be better for you than the wrinkled/wavy sheet?
I also have the 16:9 screen. I am width constrained and so it works best for me. When watching 2.4:1 movies, if you have a dark room (black ceiling, dark colored walls), and good light control- the bars on top and bottom dissapear to me. I don't notice them at all unless I look at them. It helps to have a decent black level out of the projector too.
Enjoy the setup! You'll love it when complete (with a fixed screen and Axiom sound).
