@Jeroen: I can't find the option to choose between fanart or channel logo in TV Channels. Where did you hide it 

There's no setting for this. The setting you're referring too was just a setting to choose between image dimensions that were better suited to displaying icons and image dimensions that were better suited to displaying fanart/16:9 images because in the channel list there is no distinction between icons and thumbnail image for some godforsaken reason.

The fanart images that are available are pulled in by the skin helper add-on.

At the moment it's like this basically:

• Fanart image available through skin helper -> use the fanart image
  
• No fanart image available through skin helper -> use icons.
