Peapod Podcast Download Client

It would be nice to be able to rename downloaded file based on the
information in the rss item, as well as mp3 tags. Often the tags in media
enclosures are incomplete or missing altogether, so the renaming job can't
really be pushed off onto a third party utility like id3v2 or some such.

As an example, I download Anji Bee's Chillcast, and I get files named like
this:

thechillcast-172772-08-13-2009.mp3

I can use a 3rd party id3 tagger to rename the file based on the title tag,
but if I just rename on the id3 title tag, it is often not complete, so I
get this:

Chillcast #177.mp3

But what I want is the item title, which is more descriptive:

Chillcast #177: Dreamy World.mp3

Of course, my media player is fat32 based, and can't handle colons in the
filenames, so I really need to modify that to this:

Chillcast #177 - Dreamy World.mp3

So now, the file still has the wrong id3 title tag, and it shows up in my
media player without the full title. So it would be nice to carry this
title change right into the title tag as well.

I imagine it would look something like this in a xml config file:

<?xml version='1.0' encoding='UTF-8'?>
<peapod>
<options>
<savedir>~/podcasts</savedir>

I know, I know... this is probably totally crazy, right?
