Oh fuck, that's right, that happened to me when Tested relaunched. I had 2 of every podcast because the way Zune Software refused to forget at the old items of the XMS while adding the "new" items. The solution was that when I got a new laptop that problem went away. I guess it'll be back then? Bummer. Well seeing as I'm not keeping every podcast downloaded locally anymore (Did you know there's like 20 gigs of Bombcast?) it won't be all that big a deal all in all but it is a bit bothersome.
