Comment 2 for bug 235222

Maybe I can help with this, since it's at least 6 months I'm seeing this intermittently on my PPC machine (could be related to the nv video drivers, dunno).

What happens is:
* start a movie in Totem, for example a mpeg4 video; the color is not very bright,
and sometimes a kind of sepia tone.
* go to Preferences, and look at the Hue and Saturation sliders. They're all in the middle. You can reset them with the appropriate button if necessary: the movie colors still don't show right.
* bring the slider of Hue to the right-end of the line
* now colors of the movie are back to normal: of an acceptable intensity and the movie is watchable.

The Hue and Saturation sliders seem to have an effect only on some cases and not on others; for example, I can reproduce this bug without problem on my PPC machine with an nVidia card, but those sliders do absolutely nothing no matter how I set them on my x86 machine with an i810 driver. But maybe this is a different kind of bug.

I'll try and see if I can take a screenshot of the issue -- but as I said, this bug is intermittent.
