[GIS] QGIS 2.2: GDAL Grid (Interpolation) Error

demhgtqgisxyz

As much as i understand Raster -> Analysis -> Raster (Interpolation) can provide me with a terrain file out of a shape file with a Z coordinate.
I select the input and output file and a Z field.
It gives me this error:
ERROR 6: GDALDriver::Create() … no create method implemented for this format.

Unable to create target dataset "D:/shp/terrain.dem".
GDALDriver::Create() … no create method implemented for this format.

Tried some other formats (I'm aiming for either .dem, .hgt or .xyz) but got the same error everytime. What am I missing here?

The Vector layer contains X coord, Y coord, Z coord, number and name fields.

This does seem to be related an existing QGIS bug report http://hub.qgis.org/issues/4304

You could try using gdalinfo to find the list of supported formats like:

gdalinfo --formats
