Can you explain what you mean by "wacky"? I'm not sure I see anything
wrong.

I think the problem may be your coordinate units. It looks like
MAP_PROJ_INIT and MAP_PROJ_INVERSE convert to degree coords from meter
coords (not data indices). The result you got was converting the
physical location (500 m, 0 m) to lon/lat, and not the pixel at
[500,0].

Essentially, I think you need to include the spatial resolution of
Meteosat somewhere in your code.
