Removing DRM protection from iTunes movie to watch on my TV

I'm not very technical, i've just downloaded a movie costing ?10.99 (Angels & Demons) from iTunes onto my itunes library. I want to save the movie onto a DVD and play it on my widescreen TV. I'm not interested in watching it on my laptop or my IPOD, and i don't have ?200 for a Apple TV device. I want to sit with a glass of wine and watch it on my 42" TV...If i had known i couldn't save it to a DVD i wouldn't have bought it from Itunes, i would have gone to Sainsbury's. How can i convert this to DVD without incurring further costs?

Thanks
