For some reason, iTunes refuses to delete my old podcasts of my iPod. I've have iTunes checked to only let the 5 most recent episodes of one of my podcasts on, but it will only sync all of my podcasts. This is starting to tick me off, because I want to put some movies on for traveling, but my video podcasts are taking up all of my room. I've reinstalled iTunes, restored my iPod, and delete the preference files in my library. I have no clue what to do. Any ideas?
