I wish I still had my older copies of that lens program. The most recent version seems skewed for LCD projectors. When I tried to get the mechanical setup numbers for a BG808, I had to put in lens angle of 10.5 degrees in by hand.
The resulting picture measured A from the floor up and showed the projector tilted 10.5 degrees, etc. etc. I haven't tried running it using a Cine8 as the default projector.
In short, I'm just going to compute my own setup information from the formulas in the installation manual.
To answer your question Gman, I think the picture of the CRT faces is just for reference. I wouldn't trust it. It doesn't even draw a 16:9 image when you setup for a 16:9 screen.
