This post started off as a question but turned into a solution.
My overall objective is to keep only “new” podcasts on my iPod. I am currently doing this by setting the iPod to download only checked songs (and podcasts) and then by hand, I uncheck the podcast after it has been played. I’d like to automate this.
Since I never got into Applescript, I try to avoid it. I made a smart playlist with Podcast is true, Played is greater than 0, and only checked items are included.
Then I can do (found in this forum)
tell application "iTunes" to set enabled of (tracks of playlist "Played Podcasts") to false
Enjoy!
