Thanks for confirming what I guessed. What follows is not directly related to GDAL but someone might have a solution. So... Using geotifcp I cannot assemble a JPEG-compressed TIFF and a LZW-compressed TIF keeping these compression modes for both IFD. Tiffcp can do it (but without georeferencing of course !) whereas geotifcp ouputs "JPEGLib: Bogus input colorspace". Any idea ?
