It's quite simple actually and removes all discontinuties during playback:

In input stream for libdvdnav:
 if(nav[n].start != nav[n-1].end) {
    diff = nav[n-1].end - nav[n].start;
    * return 0 bytes read to demuxer to EOF it and it flushes all mpeg packets.
 }

After demuxer EOF
 global_diff += diff;
 diff = 0;

Normally during reading from demuxer:
 packet = read from demuxer
 packet.pts += global_diff;

The main files doing this would be:
xbmc/xbmc/cores/dvdplayer/DVDInputStreams/DVDInputStreamNavigator.cpp
xbmc/xbmc/cores/dvdplayer/DVDPlayer.cpp
