Hi! I tried to capture 1.2Mpix images, then scale them down to 800x600 using hardware... and results were kernel dying.

Usually, when I set up capture with greater resolution than cca 800x600, I get 4 copies of image above each other. If you know how to get images with greater resolution, let me know.
