Can I record a box office movie?

I only want to watch it at my convenience, not back it up to DVD.
Can I record a box office film to the Sky+ box?

As far as I know you can record it and once you start watching it you are then charged, if you decide not to watch it you aren't charged.

Thank You.
As an afterthought, can I watch it more than once at no extra cost. And, is there a time limit for keeping it?
