[Qgis-user] NITF Imagery

Hello List,
 
I have several ~800MB .ntf images that I need to load into a QGIS Desktop project. I have SpatiaLite vector layers already loaded, and they, along with the project CRS, are in WGS84 (EPSG: 4326). When I load the NITF images, they do not appear to load in coordinate space (cursor coordinates are not in lat,long and they do not overlay the vector) and the images are inverted (up-side down). Loading in several together, they draw on top of one another. Initially this suggested that the image coordinates were stored in the header in rotated format without coordinate reference.
 
When I load these same images into ArcMap, they draw correctly, right-side up and overlaying the same SpatiaLite vector in coordinate space. Looking at the image properties, the spatial reference is WGS84 (GCS_WGS_1984) and the extents (given in decimal degrees) show that the image is not rotated. Looking at the metadata for the images in ArcCatalog confirms this.
 
The only thing I have been able to find so far concerning NITF is this:
http://osgeo-org.1560.x6.nabble.com/gdal-dev-Can-t-read-NITF-image-td5064590.html
(a little over my head, but this seems a different problem)
 
Could I be missing a plug-in? When I go to add a raster layer, my drop-down of raster types includes NITF imagery. Any help would be appreciated.
 
Windows 7 x64 2.4GHz 8GB
QGIS Desktop 2.0.1
ArcGIS Desktop 10.2.1
 
Thanks,
James
