Chris,
After the patch I can change, for instance, the bightness level. I can definately see the effects on my screen...
What output do you get when you do
ivtvctl -Y ; ivtvctl -y brightness=0 ; ivtvctl -Y ; ivtvctl -y brightness=128 ; ivtvctl -Y
My output is:
[EMAIL PROTECTED] ~]# ivtvctl -Y ; ivtvctl -y brightness=0 ; ivtvctl -Y ; ivtvctl -y brightness=128 ; ivtvctl -Y ioctl: VIDIOC_QUERYCTRL Brightness = 128 Contrast = 64 Saturation = 64 Hue = 0 Volume = 65535 Mute = 1 ioctl: VIDIOC_S_CTRL ioctl: VIDIOC_S_CTRL success ioctl: VIDIOC_QUERYCTRL Brightness = 0 Contrast = 64 Saturation = 64 Hue = 0 Volume = 65535 Mute = 1 ioctl: VIDIOC_S_CTRL ioctl: VIDIOC_S_CTRL success ioctl: VIDIOC_QUERYCTRL Brightness = 128 Contrast = 64 Saturation = 64 Hue = 0 Volume = 65535 Mute = 1

The attached patch will enable control over brightness/contrast/saturation/hue settings for cx25840 based cards...
The patch is made for ivtv-0.3.2d, but it will also work for ivtv-0.3.2c patched with John's audio patch. (which I like because it makes the code much cleaner...)
I don't think that this works for me. I've tried:
ivtvctl --set-ctrl=brightness=0 ivtvctl -y saturation=0
and other variations with saturation/hue/etc, but the picture doesn't change.
