/dev/video: Operation not permitted

I am trying to install a Webcam to my Debian 2.2 Laptop. I run kernel
2.2.17 and have installed the backport to get usb working. This seems to
work. Also I have the camera operational and I have installed xawtv
which (according to people who have done so) can be used to display the
camera image. If I start:

  xawtv -c /dev/video -geometry 352x288-0+0

I get:

  This is xawtv-3.06, running on Linux/i686 (2.2.17)
  visual: id=0x22 class=4 (TrueColor), depth=16
  x11: 1024x768, 16 bit/pixel, 2048 byte/scanline, DGA, VidMode
  can't open /dev/video: Operation not permitted
  waitpid: No child processes
  v4l-conf had some trouble, trying to continue anyway
  open /dev/video: Operation not permitted
  can't open /dev/video: Operation not permitted
  waitpid: No child processes
  v4l-conf had some trouble, trying to continue anyway
  open /dev/video: Operation not permitted
  no video grabber device available

I have added myself to the group video, that should be okay.
ls -l /dev/video shows:

  lrwxrwxrwx    1 root     root            6 Oct  3 17:19 /dev/video ->
  video0

Have I overlooked some obvious thing?

Thanks a lot.
