Honestly, I don't know.  I'm brand new to the code base and was just
diving in trying to make mplayer work for me so that I can rip some DVDs
to XviD.  It appears that the focus is on getting three timestamps where
the values in the timestamps are within a certain range, and that the
number of bytes needed to achieve that is just a wild guess.  That range
needs to be enlarged; do it whatever way you think makes the most sense.
