Front projection or not?

Drew, George,

I understand that you're saying that I can go 80" (92" diag) or more without watching a movie like a tennis game?

I was leaning more towards a 4:3 native aspect ratio, I notice now that there are some projectors out on the market with dual nativity.

Wouldn't the projected 2.35:1, 1.78:1 etc image occupy the same amount of space whether it's on a 16:9 or 4:3 screen? However, a 4:3 image on a 16:9 screen occupies only the middle.

The only use for this projector setup is to watch movies; DVD mainly but also the occasional VHS (older stuff). Very very rarely cable (I have no satellite), that's done on the living room tv set.

Just curious, where on the net did you get the info to build your screen?
