Disable Auto playing the next podcast on iPod's

The new iPod's play podcasts continuously, so if you decide to go to sleep with an hour-long podcast going and fall asleep, you'll wake up with a whole bunch more podcasts marked as played that you never actually listened to.

The solution:

Go to the main menu, then change the Shuffle setting from "Off" to something else. I picked "Albums". This stopped my podcasts from playing over and over again.
