I've come across some podcast links on websites that point to the iTunes store, rather than give you an ordinary RSS feed. I know there are two popular podcast apps for iOS, DownCast and iCatcher, but I'm not sure which one is the best to go for. I thought I read that DownCast really drains the device's battery, but I wonder if that's been improved if that's indeed the case? Basically, I'm wondering which app you would recommend? Alternatively, is there a way I can get an RSS feed address from one of these iTunes links?
