I see similar problems with Gutsy's driver. However, my image isn't "too white". There is no white at all: it's all blue and red combinations.

I didn't know about xvattr and so on, and it's annoying that Totem has no controls (that I could find) to adjust any of the brightness/contrast/saturation values, and the control to turn of Xv output is rather obscurely hidden in a different program (so I didn't find it).

So I tried other video players. Xine looked similar, but slightly better. Still all blues and reds but with a hint of green. Turning off Xv fixed it.

mplayer had slightly more green, yet still with the same problem. Turning off Xv fixed it (unsurprising by now).

Isn't it odd that Totem/Xine/mplayer all looked different, despite having the same problem. (Note that I always tried Totem first).

Eventually I found that the Xv Contrast control was set to its most negative value. By changing this in mplayer to a low-to-middle value, the picture was fixed.

Curiously, I am now using this driver, and Totem looks fine without touching any Xv settings:

But I also notice that Contrast is still set to that most negative value, but now changing any of the controls doesn't have any effect on the picture, in any video player (using Xv).
