cannot set WB on 550D video mode without ML

[jagnje]

Hello, I hope someone can help me..I have a 550D and I`ve been using ML with it since day one. Now I`m shooting an automotive show and the thing is that the client brings his own SD cards so I can`t use ML. Ok, I`ll live but the thing is that in video mode I can`t change WB at all?!?! what`s going on here? Do I need a FW update or something? When I press the Q button these just isn`t a selection for WB and I can`t set it anywhere in the movie menu.
What am I missing here?

There is a blank field in Q-screen. Select it and press SET button.
