[gdal-dev] Gdal_translate won't crop VRT-file

Dear list,

I run into problems with gdal_translate.exe, calling a VRT file which I 
created using the MapWindow OCX.
This is the error when I run gdal_translate.exe from the batch file, 
calling the VRT-file:

0ERROR1: Can't find RasterDMS field in Eimg_layer with block list
ERROR 1: y:\...\i21bn1_24.aux, band 1: IReadBlock failed  at X offset 0, 
Y offset 80
ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 80

It seems that gdal_translate is unable to open the grid contents since 
it produces a grid with only nodata-values.

Here's the contents of my batchfile:

     /c:\GDAL\bin\gdal_translate.exe  -of HFA -a_nodata -999 -projwin
       193199 519840 194203 518598  "y:\Dropbox\H1135 Kavelsloten
       Zuiderzeeland\Ontvangen\GIS\AHN2-Zuiderzeeland\ahn2_05_int\gridcollection.vrt"
       "C:\temp\Q4-2_CROPPED.img"/

     //pause/


Here's a fragment of my VRT-file:

Any ideas?

Thanks,
