Downloaded a podcast directly onto my ipod. Decided I didn't want it anymore, so I deleted it from my iTunes library. Next time I plugged my iPod in, it just copied it over again. Changed the podcast settings on my ipod so only podcasts I select will be on there. While it no longer shows up when I look at the list in iTunes, it is still there on the actual iPod. How do I delete it permanently? I even tried doing a factory reset, but an unspecified error prevented that.
