Even,

I tested and compared both files and they are similar (except that with 
gdal_translate I have Metadata tags). Both are not working in QGIS: no value 
in dataset! Translating into GTIFF is working but I want to keep vrt files to 
working on them with MapServer.

I can send you netcdf and vrt file if you want to test it.

Thanks,

Y.
