I saw the error messages that you are receiving on the post on Channel9... You will have to check the references for the directX assemblies that you are using. Make sure that you are not including the new DirectX assembly for the Beta Code.
There will be two different versions of the Microsoft.DirectX assembly for the sample above make sure that you are using version 1.x.x.x assemblies and not the 2.x.x. The application should now work.
