Change SmoothStreamingSource from ListBox?

Hello,

I have built a Video Player with a SmoothPlayer in it, I also have a ListBox in there with alot of ListBoxIthems in it. What I want to do now is to Bind one of the ListBoxIthems to the SmoothPlayer so that the ListBoxIthem change the SmoothStreamingSource when I click on it.

I want the ListBox to be like a Channel List where my ListBoxIthems are my Channels. When I click a channel then it should change to that SmoothStreamingSource (Channel) in the SmoothPlayer. I have spent hours of hours of trying and googleing but with no success so far.

Help would be much appreciated.
