Rhythembox MP4 Playback issues

[danielgroves]

Hi,

I have been trying to sync Rhythembox with my iTunes library which is stored on an 3.5" external 250GB freecom HDD. It says I need a to download a codac in order to do this, which it then brings up a download box, I selected the only available option which it then tried to download and displayed this error:

Can anyone decyfer this? Please can someone advise me on how to fix this as I am rather new to Ubuntu. :confused:

The message is alerting you to the fact that you have duplicate entries for the medibuntu repository in your sources.list file. Disable one of the entries and try again.
