Hi 
I've just had a quick go with umvd-0.0.3.tar.gz and renaming decoder.h
to decoder.c from gspcav2-0.2.10.tar.gz (there is no decoder.c
otherwise). Also removed all of previous working install of
gspcav2-0.2.10.tar.gz via:
$rm -f /lib/modules/2.6.24.4-desktop-3mnb//misc/gspca*.ko
$rm /sbin/gspca* 

Skype still has a green image.

gstreamer gives green image.
$ gst-launch-0.10 v4l2src device=/dev/video1 ! ffmpegcolorspace !
ximagesink

mplayer fails and generates extra /dev/video2 to video5 devices - then
need to restart the pc to remove extra /dev/video2 etc devices.
$ mplayer tv:// -tv
driver=v4l2:device=/dev/video1:noaudio:brightness=0:contrast=0

Here is syslog covering these events:

I also tried using decoder.c from gspcav2-0.2.7.tar.gz which also gave
a green picture with skype.

Camera is 046d:0928 Logitech, Inc. Quickcam Express.
Using Mandriva 2008.1

Hope that helps?

Chris.
