Hi,

well, I think (but I am not quite sure) you're both right. Hardware acceleration can be used for several purposes.

1) Decoding of media (MPEG, H.264). This should still work with ffdshow postprocessing when using a decoder like nVidia Purevideo. The software decoder routes the media stream directly to the hardware.
2) Accelerated drawing on the display (DirectDraw). This will not work, if you use ffdshow as postprocessor. This is a effect, you can also often see in the settings of DVD-Decoders. There you can only use picture enhancements if you uncheck hardware acceleration.
