    Fa> dvdauthor -o $WORKDIR -T

there is a tool called split_mpeg in the dvb-mpegtools that come with
the libdvb package. It is a simple method that I also use to jump
forward in mpeg files in ntuxplayer. It looks for the closest PES with
sequence-header given a filesize, i.e. usage: split_mpg <filename>
<size>.
