I am having a problem with my iPod/iTunes where an episode of a single podcast cannot be deleted. The episode in question does not show up in iTunes or as being on the iPod when I drill down and look at the podcasts on the iPod in iTunes. It also does not play if I try to play it on the iPod; it just waits a second and skips to the next podcast.
I have iTunes 184.108.40.206, my iPod has OS version 4 (although I was having this problem before I upgraded), and Windows 7 64bit.
I would really prefer a solution that does not require me to completely wipe the iPod because I have a bunch of WiFi keys stored that I don't want to have to dig up again.
