Sync a rented iTunes movie from iPhone to computer?

I rented a movie from iTunes earlier today on my iPhone and I was wondering if there was any way to put it onto my computer to watch it. I know I only have 30 days to watch it. I tried to sync my phone like normal and it didn't put the movie on my PC.

You may refer to this step by step guide, it's about how to transfer photos, songs, videos, etc from iPhone to computer. It works pretty well for me.
