Downloading a movie to iPad and it's "stuck", says "processing"

I downloaded a movie to my iPad2 and after it appeared to be almost complete, it now says "Processing...". It has been processing for more than 24 hours. The movie shows up in my rentals, but if I try to play the movie, it says "Cound not load movie".

I can seem to get the iPad to stop trying to "process" whatever it is trying to process.

Help?
