That is fine. Could you then show me the output of NCSFileReporter.exe ?
This file is part of the APOLLO Essentials Utilities: http://download.intergraph.com/downloads/erdas-apollo-essentials-utilities-2015
Please provide the output on both files. 

Regards.

Hello Jacek
I'm using gdal  1.11, binaries  downloaded from gisinternals with the ref 1600 gdal_translate -formats gives me that for ECW:
  ECW (rov): ERDAS Compressed Wavelets (SDK 5.0)

In Qgis valmiera i have several gdal dll, so i'm not sure which one they use

And in worldwind it's a custom build, using gdal 1.7.2

Unfortunately I don't think i can share the file, I've to think of a way to create another ecw and copying the metadata, i could not using gdal_translate

Regards

Nicolas
