Unable to play orkut videos on my computer Plz help

I am unable to play orkut videos on my computer. What I need to install so that they play ?

Me running windows xp and using internet explorer ..

You don't need anything to install, those videos are flash files. Its mostly with IE but if it is not then install it from here:

If still not able to play then there is something else !
