Viewing photos using DLO HomeDock for iPod

I just purchased an iPod 60G and am trying to view photos on my tv using the DLO HomeDock for iPod. I am able to get the audio to come through the tv but cannot view photos or video. I have the AV cables hooked up correctly and even have an S-Video cable hooked in. Does anyone have any insight as to why I can't view my photos? Any help would be greatly appreciated.
