Thanks for looking into that.  Very nice.  By the way, I have a good working
relationship with Dan Dennedy (creator of MLT).  I don't think getting the
python-mlt patches approved should be that big of a deal, assuming they make
sense to him.  When we are ready to send the patches to MLT, let me know and
I can contact Dan and let him know what's coming. =)

Thanks,
-Jonathan
