Aah, interesting.  If it does work, you might be able to mark the
cut-section as a chapter and then use the DVD's scripting to
automatically skip over the chapter on playback.  The cut section
would still be in the MPEG stream and take up space, but maybe you
don't care if you're only trying to archive shows..
