To clarify what I see it looks like the red and blue colour components have been swapped. What should be red in the videos appear in blue, what should be blue appear in read, what should be green does however appear in green.
I upgraded from 11.04 to 12.04, and the problem persists. This computer was able to play youtube videos without problems when it was still using the preinstalled Ubuntu 9.10. So the regression happened somewhere between 9.10 and 11.04.
