The SetBump method temporarily changes the playback, for synchronization of multiple external devices.
HRESULT SetBump( long Speed, long Duration );
[in] Specifies the temporary speed (a multiple of normal speed) as a long integer.
[in] Specifies the duration of a bump as a long integer. The duration is given in the current time format; see IAMExtTransport::SetTransportBasicParameters for more information.
Returns an HRESULT value that depends on the implementation of the interface.
This method causes a temporary speed variation of the transport. The transport operates at the new speed until the specified duration elapses. Then it returns to its previous speed.
MSDV does not support this method. It returns E_NOTIMPL.
