Hi,
For some reason Gilbert Gottfried's Amazing Colossal Podcast (http://feeds.sideshownetwork.tv/GilbertGottfried) episodes are appearing 3 times each in the episode list, with a 1/3, 2/3 and 3/3 at the end, and as a result auto download will download all three.
This is also the case for subscribing via the podkicker pro iTunes search as well.
Don't know if it's them or podkicker pro, however, have tried Sony's Music app podcast facility & have spoken to iOS iTunes users and in both cases, there's no problem (1 download per episode).
For now I've disabled auto download and enabled notifications for this podcast, but it would be great to know if it's podkicker pro needing a fix, or Gilbert needs to sort out his rss feed
