[d] enclosed in brackets chaotic perfectionist for hire

I need some help. Right now I use iTunes for all of my podcasting goodness. I'm not sure that I like it though... It's mostly good, and I mostly like it. They're pretty well managed, and I can edit what I need to (most of the time), but I can't add externally downloaded podcasts and have them show up in that directory.

I'm looking for something else (maybe), and I want to get some recommendations. I already looked in a couple of places (like Podcasting News and Wikipedia), but I'd like some feedback on what other people are using before I start installing everything.

As far as features go, I'm looking for something that works like almost a cross between iTunes and Picasa, but for audio. It would allow me to subscribe to podcasts and manage them, and (hopefully) have bittorrent support... I'll leave the rest open for now.
