Question : can not display online video

My laptop could display CBC online news (video+audio), but only show video of CNN.

so i download Codec Pack All in 1 and installed it, after that  it could not show the video of CBC ,but only the audio,

it could not show the video of CNN also.

I remove the Codec Pack All in 1 from my laptop, it still the same.

can somebody  know how to fix it?

thanks
