I did as soon as I read your message and, WOW, the driver has improved a
lot! Now camorama does not lock up (although it shows a triple image) and
permits changing the settings (brightness, contrast etc.) and camstream
shows the image as mplayer. However, the image is incredibly dark, and I
couldn't even see anything if I didn't point it to the lamp of my room. You
can see how it appears here: http://patola.org/lamp.png
