I finally succeded in calculating both the current and total time !!!
It calculates the total time in libmpdemux/open.c,open_stream() using

dvd_playback_time = dvdtime2sec(&d->cur_pgc->playback_time);

and the current time using

pts = dvd_playback_time * (demuxer->filepos - demuxer->movi_start) / 
(demuxer->movi_end - demuxer->movi_start);

Here's the patch for 1.0-pre7try2, it works perfectly for me.

Any comment/feedback is appreciated...

Bye
Davide
