Did you know VM subscribers can download movies to their iPhones or iPads? It used to be a service exclusive to Sky Go customers but the latest version of the Sky Cinema iOS app has 'download' as an option.
Downloaded movies stay on the device for a month but once you start watching it they expire after two days.
I haven't been able to check if they can be viewed on a TV via HDMI and sorry but I don’t know about Android devices.
