I've been trying to get ADPro to make a decent GIF out of screens saved as
24bit IFF (ILBM?) from DCTV.

The problem is, when I examine my work on a SVGA display or truecolor Xterm,
the results are really hideous (banding in color and poor color choices).

I have the palette set to 'enhanced' and I'm 'executing' with 256 colors.
When I view with 'xloadimage' on a UNIX system, it reports that about 250
different colors are in the colormap, apparently ADPro just didn't get very
good approximations. 

Also, if I use 'color_to_gray' and save a GIF, the file size increases from 
about 79K to over 120K and apparently has MUCH more detail (more gray shades
where single bands of color used to be).

Any ideas? I'm using a friend's ADPro, so it's hard to just spend hours 
messing around trying to tweak it right...
