Hi Alejandro, Your data *is* the problem, please add the coordinate system info. Using the --xx etc options really is not a good solution going forward. Use properly set up data and things will work fine. Please go check out the gdal website for info on how to set up your data.
As for VPB docs, I haven't had a chance to write full docs for all the utilities yet. There are some notes online. Robert.
