So we have now decided we are going to install a 110" wide, Screen Research, cinemascope curved screen. Still have a couple of questions in mind.

1) What's the best way to determine the projector distance for this. We are using an Epson 9500 and its anamorphic lens. Is it likely going to be installed further back or closer to the screen to create the geometric distortion required?

2) The client asked, "What's better, 2.35:1 or 2.40:1 ratio?" I recall seeing something on AVS claiming that 2.40:1 was better or something. Are these really even options with cinemascope projection or are these really the same thing just rounded off to an even number?
