Hi Jorge, Your two images stacked together look great (page 6 in your PDF)!
Like you, I am able to stack images with 4 bands (RGBA) in QGIS, and that is how I use them. I have not been able to figure out how to merge or build a virtual raster from them! In my experience, both the virtual raster (gdalbuildvrt) and the merge (gdal_merge.py) combine the alpha channels of ALL the images, and then apply that combined alpha to a mosaic of the other bands. This is why you get the white band along the cutline. I get the same thing. I have never found a way around it. What we need is a tool that applies the alpha channel WITHIN each image, and then merges the results. Perhaps someone else out there has an idea?
