[Qgis-user] Problem with VRT format

[Patrick Giraudoux]

Dear lister,

I meet a problem trying to wrap layers 10, 20, 30, 40, 50, 70 of 
landstat ETM into a VRT format. Everything goes well including writing 
the VRT file via the raster menu (see the result below), BUT when I load 
it from QGIS and try to find the layers in the "properties" (mutiple 
band colors), I can just access to "band1 (grey)"...

I am working with QGIS 2.2.0 Valmiera under Windows 7 pro.

Any idea about what happens ?

Patrick
