Paul,

Unless the fix has yet to land in the repositories, it's not fixed in Feisty. It's a bug in totem's GUI, I think.

Again, my system: Dell Inspiron 510m, Intel 855GM, running Feisty with everything up-to-date.

Steps to reproduce:
1. Open a video in totem (gstreamer), then go to Edit, Preferences, Display, click "Reset to defaults" and close Preferences window. Notice the colours are all washed out.
2. Keep the same movie playing, and in a terminal invoke "xvattr -a XV_CONTRAST -v 64". The video's colours will look normal.
3. Close totem, and open the same video with vlc (making sure it uses xv output, as default). The colours should still look good.
4. Close vlc, and once again open the video with totem. Colours are bad again!
5. Close totem, and open the video with vlc. The colours are still bad.

The problem is with totem's GUI. Totem thinks that XV_CONTRAST should default to 126, and resets it every time the application starts, ignoring the system setting (as opposed to apps such as vlc, that respect the setting). The only solution is to manually adjust the contrast slider in totem's GUI until it's at 64 (which can be verified precisely with xvattr as you adjust).

The bug is still present, and it needs to be fixed either in totem's GUI, or via a change to the i810's contrast values. In other words, XV_CONTRAST=126 is the default, but it needs to be around 64.
