Still looking into this problem, i've run gdalinfo with -mdd VERSION, output is :
Metadata:
  COLORSPACE=RGB
  COMPRESSION_RATE_TARGET=10
  VERSION=2

Looking on http://www.gdal.org/frmt_ecw.html, i may be facing backwards compatibility issue with a V2 file, something i was not expecting since V5.x ECW plugin is supposed to be backward compatible. Using gdal 1.7.2 i have no mdd at all, and no srs reported but somehow the map coordinates are good when importing it in Worldwind. Could it be related to the plugin compatibility issue related there https://trac.osgeo.org/gdal/ticket/4635 ?
