gPodder

gPodder is a program for organizing, subscribing to downloading, and tracking your podcast subscriptions. It is intended for use on a desktop or on a mobile device, like the N810/N900 from Nokia.

It can play video or audio content, and like a good Unix program it calls an external player to player your media.

They accept donations here http://gpodder.org/donate.html, either directly through PayPal or by some gift lists that the authors maintain.
