The xine player works very well with the output xshm but I'm using mplayer and it fits well with the work output to gl as x11, but really do not like its interface. I'm trying to use the gmplayer it but the color setting is not saved, if you close the program I have to adjust the colors again. weird. Maybe go back to Hardy Heron does not know or Windows. Thanks anyway.

Do not install it nothing, nothing removed.
I haven't changed the xorg.
I haven't changed the nvidia x server settings tools.
In gstreamer-properties -> video output-> custom-> pipeline:
tried several commands, which ran:
videobalance hue=-0 saturation=1 brightness=1 ! videoscale ! ffmpegcolorspace ! ximagesink

[...]
--
videobalance hue=-0 saturation=1 brightness=0.25 ! xvimagesink
--
videobalance hue=-0 saturation=1 brightness=0.25 ! autovideosink
--
The best command was "videobalance hue=-0 saturation=1 brightness=0.25 ! autovideosink"
For the internet I found some tips to "videobalance hue =- 1 ! Autovideosink" or "videobalance hue =- 100 ! Autovideosink" I decided to include the parameters you wanted, saturation and brightness using whole numbers and it worked.

The totem ran all night without problems, videos wmv, flv, avi and mp4 and mp3 with effects.
We do not understand why removed the totem-xine, which I personally think better and easier to configure. In ubuntu 8.04 xshm used, configured in / home / folder User / .config / totem / totem_config with everything ok. Pitty
This setting doesn't affect the players xine (xshm ) or mplayer, both are still working (saturation and brightness, etc.).

Hope that helps.
