That looks exactly the same as a DTV STB set for 16:9, but being output to a 
4:3 TV set.

On a 4:3 monitor that can't zoom, my bet is that the image SHOULD BE only be 
viewable in postage stamp format, if the BD player were set correctly.

Yes, but that would be correct for painting a 16:9 image, with black columns 
left and right, on a 16:9 screen, right? And the image would then be stretched 
out to a 4:3 actual image aspect ratio (the rest being the black columns).

For whatever reason, you are sending an image to the 4:3 monitor that is 
expecting to be viewed on a 16:9 monitor.
