That is why we asked if you were watching primarily movies on that screen (and 4:3 on another TV).
Sorry I forgot to answer that question. No, we would not be using the theater setup for primary 4:3 viewing. I expect to use it for sporting events and those TV programs that deserve special treatment such as the X-Files, Star Trek, and programs broadcast in surround sound.
Your setup and custom masking looks very nice. http://www.avsforum.com/ubb/smile.gif
Do you use the RPTV for regular TV viewing and then drop down the screen for movies? Very efficient use of space.

Have you considered suspending your projector from the ceiling? What kind of ceiling do you have and how high is it? What size of room do you have? Many installations with those kinds of issues end up with projectors attached to a pole off the ceiling.
The room is 16.5'(screen wall)x 20' long. There is a large window that opens to the street on the back wall (which is why we can't install the projector there). The wall height is 9' up to the crown moldings, then the ceiling slopes diagonally up to a higher flat ceiling which is 11.5' in height. The ceiling is sort of a 3D trapezoid, if you can visualize that. I seem to recall someone telling me that it is called a coffered ceiling, but I could be wrong.
I am reluctant to do a permanently suspended ceiling mount because it would significantly detract aesthetically from the room's other function as a living room which is right off the main entry. Any sort of ceiling mount would have to be a lift mechanism, which is challenging given the ceiling height there at 11.5'. Although there is attic space above the room, the roof of the house slants right above there, and there is question whether we could fit a full lift mechanism above the ceiling. We have thought about using a lift but was leaning toward the console solution because it seemed easier to do (less labor/construction, complexity, and cost). But if a lift is our only viable option because we can't find a projector to work with our throw distance, we will have to revisit it.

This may be a relatively minor point but choosing a constant height screen such as a 2.35:1 and masking only the sides does have some resolution issues.The largest image will be the 2.35:1 sources and this also happens to be the source with the lowest amount of inherent resolution to work with.
If I understood your comment correctly, this is why I was thinking of a 4:3 screen, because that allows us to maximize the number of pixels used for each aspect ratio.

Well, the most common screen size for DVDs is 16:9, so I would agree with your A/V installers on that point. Also, don't forget that if you plan to sit 10-11 feet away from a 72"x96" screen, then be prepared to be disappointed. Afterall, most all 4:3 viewing is the lowest quality video source (ie, DSS satellite, VHS, or cable).
I didn't know the most common screen size for DVDs is 16:9. I thought it would be either 1.85:1 or 2.35:1. And your point about viewing low-quality 4:3 sources on such a large screen is well taken. Looks like we're back to 16:9 as the best option.

I bought a 100" diag 4:3 screen. Im not sure of the dimensions. At 10-11 feet wide screen movies were perfect. But if I watched 4:3 source I got a headache and my eyes got tired. I figured that with 16:9 movies my eyes were looking left and right, but with 4:3 I was looking left, right, up and down.
This is also a good point. You guys all have great ideas and suggestions. This forum rocks! http://www.avsforum.com/ubb/smile.gif
Is horizontal masking on a Stewart much more costly than vertical masking? Is this because of the bottom mask panel that must raise up? Is it possible to get top horizontal masking only to lower the cost? I think with a Faroudja processor, we can shift the image down to the bottom of the screen for 2.35:1 to eliminate the need for a bottom horiztonal mask.
