playing video in iOS 5 - ios5

Question

I am trying to follow this tutorial link, but i have issues. Can somebody please have a look and let me know what needs to be changed.
I tried to looking up other examples but none seems to work. Please let me know what needs to be changed.
The following is the error

objc-class-ref in VideoScreenViewController.o

Add MediaPlayer.framework to your project..and then try..

Answer 2

i had the same problem today and i found out that the media player framework has to be added correctly: so at first right click on "frameworks" click on "add files to.."
located the framework within the folder "developers/Platforms....etpp" then click on "create folder references for any added folders" and click "add" finally - thats it. After this the error did not appear anymore.
