Tried to listen to some old podcasts and discovered this. Only the latest podcast for each podcast category plays for me. Like when I open Giant Bombcast under the podcast tab the latest one that it loads plays. But if I try to listen to an older one it doesn't work. I can't even download it. When I try to save the MP3, it's just an HTML document. I'm using Chrome as my browser, but tried it on IE also. Same thing.
Hope this helps you.
Also anybody else?
