There is only one instance in which ffdshow uses one feature of dxva acceleration: performing video deinterlacing (when playing interlaced mpeg2 video from dvd's for instance) and having "HW deinterlacing" checked on the ffdshow video decoder configuration page -> Output panel. This only does deinterlacing, as the name says, and the two methods specified there (Bob and Weave) are nothing amazing. Better use a software deinterlacing method, by enabling the "Deinterlacing" panel.

There are no other instances in which ffdshow will use any dxva features.
