Problem : 

When Windows Aero is turned on at Windows* 7 or Windows Vista*, the simpleplayer application in Unified Media Classes (UMC) sample does not render any video with the error message:

"Error in video render"



Root Cause : 

The UMC DirectX* render sample uses old function interfaces and does not work with Windows* Aero. Users need to disable Windows Aero if they run the simpleplayer application.

When users add UMC DirectX render sample code (dx_drv.cpp) in the application, the DirectX render also does not work correctly at Windows* systems with Aero enabled. 


Workaround : 

The workaround for this problem is to disable Windows Aero to run the simpler player applications. When users add the DirectX render sample code (dx_drv.cpp) in the application, they can use the attached file is to temporally disable Aero.

The problem was fixed in Intel IPP 7.0 release.
