[? YouTube ] How can I control the end state of the video?

I have many embedded videos from YouTube and I want to control the ‘end state’ of the video after it has played. At present it shows links to other videos and some of them I don’t want to have on my site. How can I control this aspect of YouTube and does this plugin do it?

I am not yet using Viper Video as I’m still looking for a solution to this problem.
