Hey guys. I am a brand new iPod user, and I bought an iPod nano 8 gig a couple days ago. A major draw for me was to be able to watch my video podcasts whenever I was away from my macbook. The thing is, those videos take up some space, and I like to keep my iPod clean. Is there anyway that I can have iTunes auto-delete the podcasts I have already watched when I sync it? Thanks for any advice.
