The Media Center Sandbox

I have n weird problem with AddInHost.Current.MediaCenterEnvironment.PlayMedia() method.

When the application starts, the first video is commenced by the constructor method, and I can watch.

Then if I select another video from the menu, the current playing video is not showing( it is normal :) ) but I can't see the new video? I am not getting an error.

This is the code I only use:

AddInHost.Current.MediaCenterEnvironment.PlayMedia(
MediaType.Video,
myVideoLink,
false
);

Do I have to initialize the AppInHost? Which steps I have to follow to show the videos to the user in sequence?

Thank you for your help..

Ahh sorry guys it is my mistake..

I checked the video link and realized that the second video link was wrong.. :) Now everything is working properly.
