Problem with installing amarak-extras-nonfree

[bourne553]

I should mention that I am still very new to linux and am learning as I go along here so please bare with me and my stupid questions.

I have been looking into getting Amarok to play MP3s. I have attempted to in stall the pacakge: 'amarok-extras-nonfree'. I have read that this will allow your system to play MP3s, or is at least apart of the process. However when I did the yum install 'yum install amarok-extras-nonfree' I get the following error:

I am just wondering why I am getting this error and if there is anyway to get around it and install the extras? Or is there another issue going on?

I attempted this tutorial: installing codecs but that didn't help at all. I am just wondering if that might be what is stopping the extras from installing?

Any help would greatly be appreciated

thanks
