So, there is an interesting configuration problem on first upgrade or install of Karmic Koala the latest offering from Ubuntu.
It’s a very easy fix, as the hue setting in totem is set to the extreme left causing all video players to render with a blue hue. To correct open totem movie player click on Edit -> Preferences -> Display and then slide the hue slider to the middle.
