Music Video Downloaded From ITunes Causes iPOD to Hang

I'm a new user. Downloaded a video (Pink Houses) from iTunes. At end of play, causes iPOD to hang. I know how to do the reset thing. I will pursue deleting video from iPOD and re-synching with iTunes. If problem persists, is there a way I can download the video again into iTunes without having to re-purchase? Have other videos that work fine. Would like to solve this problem rather than live with it. Thanks for any help.
