Ok, I should have almost everything checked in to libdvdread cvs now.
Watchout though as it's not binary compatible with the old version.
Will bump the .so version when making the next release.

Hehe.. yeah figureing out the corrent PG or Cell and jumping there would
be a nice first step.  Then one should easily be able to tweek the
exact VOBU address and take it to just the rigth place.
Currently I think you'd have to do something along the lines of the code
in  vm_resume_int.  given seek_cellN and seek_blockN (seek_blockN beeing
the block offset for the VOBU one wants to jump too).

    state.cellN = seek_cellN;
    state.blockN = seek_blockN;
    if(update_PGN()) {
      /* Were at or past the end of the PGC, can this happen? */
      assert(0);
      link_values = play_PGC_post();
    } else {
      link_t do_nothing = { PlayThis, 0, 0, 0 };
      do_nothing.data1 = state.blockN;
      link_values = do_nothing;
    }

There migth be a buch more info that needs updating haven't though about
this all that much so far.

Ok, seems ok, I'll give it a look together with Bjorn.
We migth want to export some othe info too I guess, could put that under
a different call though.
