   I think this boils down to the commercial players following a path through
the IFO files based on the end user actually navigating the DVD through the 
standard menu rather than trying to treat the DVD as raw data.

   I think this is why VLC can navigate the menus of a "broken" DVD even when
tools like vobcopy or even "mplayer -dumpstream" will choke.
