Backup Podcasts

Hello,

I was wondering if anyone is able to explain to me how I can backup podcasts from my Podcast App on my iPohne 5 to my computer. I used to be able to do this on itunes before there was the Podcast App, but now they don't show up on my iTunes. Is there any way I can backup my pocasts as I like to keep them so I can listen again, but they are taking up too much rppm on my phone (I have over 4GB of Podcasts on my 16GB iPhone 5)

Thank you
