I can set mine up two ways (at least) and to my eyes they give identical results.
1. Keep output aspect ratio at 1.78 (16:9). Set input aspect ratio to 2.35 using the new remote command for 2.35. Then adjust the input size (top left and bottom right) to fill the screen when viewing 2.35 image. I use the GetGray calibration DVD which has a pattern with the 2.35 marked in blue. Works great.
2. Set the output aspect ratio to 2.35. Set input aspect ratio to 16:9 and push zoom to fill the screen.
I have #1 stored in Mem A and #2 stored in Mem B and can switch back and forth. Nobody can see any difference in the two images except for a slight change in size. I'm using the Naomi Watts' hair in the King Kong HD-DVD to spot any resolution differences, and I can't see any difference in resolution between the two methods. Consequently, I use #1 for convenience.
I don't set both input AR and output AR to 2.35 as that doesn't seem to work for me.
