Best solution for a self hosted podcast (on WP) without Itunes

I’m working on a site build for a client who runs an internet radio station. He has interviews he has done with different celebrities and he wants to set up a podcast feature that will have three different sections (comedians, actors, musicians) and then one that will just have every podcast available for their regular shows. Which will have only so many displayed and the rest are premium on-demand podcasts.

So I’m trying to crowdsource what my best options are. There is no Itunes feed, because…he hates apple. I know, I know- but he doesn’t want to use apple products.

Honestly- i’ve done nothing with podcasts to this point- so if anyone can help me with suggestions- I’d be quite appreciative.
