actually yes it is wrong... not at all the value taken from dvdread 
itself, in lsdvd, i just use:

ifo->vts_pgcit->pgci_srp[ifo[title_set_nr]->vts_ptt_srpt->title[vts_ttn - 
1].ptt[0].pgcn - 1].pgc->playback_time

not that i actually undersatnd what's in it... I can understand why 
mplayer mightn't be able to take such a direct approach to accessing it, 
what with needing to via a comprehensive demuxer and all that stuff
but this total time does shed more light on quite why the dvd seeking 
still basically sucks when everything is so so good.
