This goes right back to the original patchset I created for adding 
trickplay specifically for Kasenna servers. It's probably no longer 
required actually. These trickplay patches go way back to the 
pre-release of 0.8.4 and at the time, I needed to ensure that d_npt was 
0 so that in the playMediaSession call further down, a -1 was passed 
over. IIRC we had problems where d_npt wasn't 0 and so when we 
un-paused, we wheren't resuming from the exact same spot.
            if( ( b_bool && !p_sys->rtsp->pauseMediaSession( *p_sys->ms 
) ) ||
                    ( !b_bool && !p_sys->rtsp->playMediaSession( *p_sys->ms,
                      d_npt > 0 ? d_npt : -1 ) ) )
