How do I stop iTunes 11 from downloading TV shows?

I can't find where to stop iTunes 11 from downloading tv shows from iCloud.

In version 10, you could stop (or pause) any show from downloading, but I can't find where to do it now.

What's really frustrating is that it's now downloading about ten episodes of past programs I've already watched on iTV and don't want to download right now, and the four unwatched episodes of another program I want to download to put on an ipad are seeemingly stuck (I presume) at the back of the queue.

Any help appreciated.
