Hi,
because you are building an illegal direct show graph, if you are using "ffdshow video decoder". As the name says this filter "decodes" the media stream. It replaces your original mpeg decoder, which you have chosen in MP settings.
See attached screenshots. I am using the nVidia mpeg2 decoder for TV and DVD. If I add "ffdshow video decoder" it is not used as postprocessor, instead it replaces the nVidia decoder. The "ffdshow raw filter" is really a postprocessor. It is added after nVidia has decoded the media stream.
You can use the "ffdshow video decoder" as mpeg2 decoder within the MP setting. This way you do not need to add the raw filter as postprocessor.
HTH,
