XNA Kinect background removal

XNA Kinect background removal

I've run into samples for this requirement, but the code I found seems to
be deprecated.
Here's the deprecated code I found: Kinect background removal
It all uses the obsolete Microsoft.Research.Kinect DLL and the 'Runtime'
object. With the current SDK we should use the Microsoft.Kinect DLL.
Does anyone know of a sample that uses the new DLL? I have seen this
sample in
http://digitalerr0r.wordpress.com/2011/06/21/kinect-fundamentals-3-getting-data-from-the-depth-sensor/
, but it displays the entire camera frame. Not just the player (without
the background).
I've tried to combine that solution with the code from the samples with
the obsolete DLL, but have not been successful with the syntax. Does
anyone have a solution?
Thanks a lot.
