Dear Katrin, just to make sure you're on the right track: is your imagery aerial (taken from an airplane) or is it satellite imagery? As far as I know, GRASS only supports ortho-rectification for aerial imagery, but cannot ortho-rectify satellite images yet, e.g. like Quickbird or Ikonos Imagery.
I had this issue a couple of months ago and had to switch to OSSIM (Open Source Software Image Map [1]) for ortho-rectification of Quickbird Imagery. Good luck!
