Kevin,

It isn't clear from your posts which, if any compression schemes your legacy app supports. LZW was patented by Unisys for a long time and many versions of LIBTIFF disabled the code to support it. You might try the -c packbits option with tiffmedian to see if it can read files compressed with that algorithm or run your newly minted palettized images through tiffcp to apply one of the other algorithms to see if the issue was the Unisys patent on LZW compression.
