I don't see that you received a response on this. My understanding of  
this, and someone will hopefully correct me if I am wrong, is that  
reprojection only works on vector data. If you save a reprojected  
layer as a shapefile, it will still have the original projection  
properties of the imported layer. So it is not saved with the new  
projection. Raster data is never reprojected on the fly (or warped).

You will need to look at gdal_warp and ogr2ogr if you want to do warps  
and reprojections of raw data.
