It's a bug in dshow aggregation of seeking interfaces, but only WMP hits it
because of the way it uses the seeking interface. You need to report the
same capabilities from all pins and return S_OK from SetPositions even if
you don't seek on that pin.

The standard way to select which pin does the seeking is that the first call
to SetTimeFormat sets that pin as the seeker. Other pins are ignored. Then a
call to SetTimeFormat(TIME_FORMAT_NONE) releases that pin.
