tv show still downloading on ipad after downloaded to itunes?

So I've downloaded a tv show onto my ipad. It tells me that because it's above 50mb I'll have to use my itunes. So I've done that and it's DL'd, but when I go to sync it to my ipad nothing happens, and I also note that my ipad is still trying to DL it..?? Any suggestions on what's going on and how I can sync it to my ipad?
