I love bashpodder!  It works, and I learned the xsltproc command because of it.
 How cool is that?

I have attached a modified script that I'm using.  It's not fully tested, but,
you may want to pass it around for evaluation.  It adds a trap handler to deal
with having the script get killed (when I shut down the system).  The cleanup
code takes care of writing out the playlist.  Also, I added some code to prevent
two copies of bashpodder from running at the same time.  This way, I can run the
cron more frequently, without risk of overlapping downloads.
