Steps, how to 100% reproduce this bug WITH loading the Live-CD and watching elephants dream, Avi,mpeg4, 1024, http://orange.blender.org/download

1. tried with ubuntu 6.06.1
* problem does not exist in this version

2. tried with 7.10
* opening gconf-editor (it lets you take a look at the values, and you can see changes live)

Values in totem after booting up the live-cd:
brightness 32767
contrast 32767
hue 32767
saturation 32767

Values after watching the video first:
brightness 32639
contrast 16191
hue 32767
saturation 8135

Values after second watch:
brightness 32382
contrast 15934
hue 32767
saturation 8007

Values after third watch:
brightness 32125
contrast 15677
hue 32767
saturation 7879

3. tried with hardy heron, daily build, live-cd, 25.02.2008

Values after boot-up:
brightness 32767
contrast 32767
hue 32767
saturation 32767

Values after first watch:
brightness 32125
contrast 16191
hue 32767
saturation 8135

After second watch:
brightness 32382
contrast 15934
hue 32767
saturation 8007

after third watch:
brightness 32125
contrast 15677
hue 32767
saturation 7879

some final words:

* disabling compiz doesn't help
* playing videos with mplayer doesn't lower the values
* lower the values with totem does affect mplayer/kaffeine output sometimes (i am not sure how often)
* choosing gstreamer-properties->video->No XV -> it stops changeing the values by totem

are there any other infos needed?
