What podcast app are people using on their macs these days

Hi,
I know there are a lot of podcast players for mac. But I simply want to download the podcasts that I like, convert them to a smaller bytrate, then put them in my archive queue to play in my player (not necessarily a podcast app) of choice. So what is the best app for downloading podcasts to an external hard drive, that won't make a fuss when I move them around. Downcast has a fit when heaven forbid, the artwork is missing. I delete the artwork, because I don't need it. Downcast also tends to panic when I move episodes. Is there simply a podcast downloader out there that's accessible with voiceover, where I'd have more freedom to move and manipulate the audio?
Thanks
