Since mplayer is open source , someone who is able to do changes on that 
should contact someone at mplayer/xine.
I think Nico Sabbi is working on dvb area on mplayer side. Further i 
think mplayer is checking very closely sync issues. For most stations 
the video stream  should fulfil the task of the PCR stream, but here 
people that really know what they are talking about should step in ;) 
Furthermore mplayer-dvb list might be applicable.
