Problme Viewing video over TV?

[gmagnes]

I have an Iphone 3G. I'd like to view some of the videos that I've purchased and can view on the Iphone over the TV if possible. I bought a cable on Ebay that connects to my device and can connect to the AV jacks on my TV or similar device (audio left/right and video in). When I connect it and try to play something, I can hear the audio but see no picture. I am on the channel on which I'd normally view video, such as from a DVD.
Anyone have a suggestion for what I can do to make this work?
Thanks,
Gerry
