There is no dedicated method to step back in DirectShow (as such existing for stepping forward). Yes you can use
IMediaSeeking::SetPositions, however but note that it is not DirectShow itself who implement it, but actual underlying filters, so support for re-positioning depends on filters and implementation, and may be limited to, for example, stepping through key frames (splice points) only. DirectShow.NET is onyl a wrapper over DirectShow and it also does not add anything on top what DirectShow offers for stepping.
