[Eli Adam]

Marius,

I don't know about 1. but possibilities for 2. and 3 below.

Does sample.tif exist?  If not, the docs say you need to use -tr or -ts, "Since GDAL 1.8.0, the target GDAL file can be created by gdal_rasterize. One of -tr or -ts option must be used in that case."  I don't know why that error would not also come from 1.
