Widescreen but details suggest otherwise?

Just a quick one.
I have a R1 movie that is labelled widesceen 1.85:1.
But when I load it up in CloneDVD2 the information panel tells me it is NTSC 4:3 720x576.
Hah?

Very likely a “letterbox” widescreen (4:3 picture with big black bars) and not “enhanced for 16:9 tvs”.
