I've been having problems with podcast listings on my iPod Touch where the podcast appears on the iPod Touch, but does not show up in iTunes. I could delete these podcasts on the Touch, but they would never go away. After reading about auto purging of listened podcasts, I played the podcasts in question, oldest to newest. The "phantom" podcasts were essentially empty (1 or 2 seconds long) and they all "played" in a second or so.
Once they were played, I could delete them on the iPod Touch, and after syncing with iTunes, they were still gone. Yay.
My remaining problems appear to be podcasts with improper metadata in specific podcast episodes. The July 8 edition of "On The Media" copies to the iPod and is visible on the iPod, but does not appear in iTunes on my Mac. No content is apparently copied as the podcast plays for a second then stops.
My workaround to make these broken podcasts playable :
- Convert podcast to AAC (from right-click menu)
- Copy podcast to iTunes
- Set Genre to "Podcast-Other"
- Create smart playlist on iPod to show these podcasts
