Yes, I am using an LT150. Yes, the width is 92". My screen is 4:3 (92x69), but I actually only pull it down up to 16:9 due to room/stereo cabinet constraints. The screen is about 12 feet from the projector for widescreen material. When looking at 4:3 material I move the projector in a few feet and up a foot or so to shrink the image to fit the screen.
Currently I am using an empty box and books to match the correct height for the widescreen mode, until I think of a more aesthetically pleasing approach. In 4:3 mode I can use a low small table.
Seating is a large couch and a large chair on either side of the projector. Normal seating is 12 feet back, giving slightly more than a 1.5 ratio to the screen width. The front of the couch is at an angle and about 9 feet from the screen.
The couch and chair are moved in as close as possible, with the projector between them. Because the projector is below the seating position and between the upholstered material, it masks the noise a lot.
I am using a Radeon based HTPC so scaling is great. Per Frode's message, I do see MPEG artifacts. However, the 1.5 distance ratio makes for a very theatre-like field of view which my guests and I find terrific.
I wouldn't put a bigger screen in my space, but I also wouldn't use a smaller screen!
One way to think about screen size -- where do you like to sit in a movie theatre? In the front, in the middle, or in the back? I don't like sitting in the back. I like the middle or even closer.
Don't forget the masking. It makes a tremendous difference. With help from my girlfriend, I've come up with a velcro, felt, dowel, and screwhook system which is completely removable when not in use.
