UPDATE! Desktop Movie and WINDOWS 8 - It seems that this is not a bug, but MS intentionally disabled using overlay mixer for all applications but the ones listed in the registry. Registry patch is now compiled to the executable. On the first run Desktop movie applies the patch on Windows 8. For other applications that can not run because of this restriction you should create a key if it does not exist in: HKCU\Software\Microsoft\Direct3D\Shims\EnableOverlays create a DWORD with the path and name of the application you want to enable overlay and set the value to 1. eg. "F:\\BP\\COMPILED\\Public projects\\desktop_movie\\dmovie.exe" =dword:00000001. Restart and you should be OK.
