Hi again,
I have now tried with a fresh machine/image with Windows 7 64bit and HW drivers. I have installede SAF500svn.exe from 9th of November and DirectX-11 from june 2010 as the only installed programs. When I try to play the sample movie Graphstudio, I only see a black window. When I try in WMP it is playing nicely. I have attached a screendump from Graphstudio. Is there any log files or elsewhere that I could learn something from?
Must be problem with you GPU drivers (DxVA seems to be not working).
Try to disable it START-SAF-FFDShow DxVA decoder, uncheck h.264 decoding.
