LedbyLight is trying to watch a downloaded Amazon movie. Amazon allows users to download movies and shows via the iOS app for offline viewing. There would be no DRM verification over the internet, as the DRM would be time-sensitive and embedded.
This is similar to how iTunes allows rentals to be downloaded for offline viewing. Embedded DRM blocks the user from accessing the video 24 hours after the video is first accessed. Amazon's DRM is slightly different. According to an Amazon help article, "The time period you have to view a downloaded video while your device is offline varies by title."
I have done this with Amazon and iTunes movies for viewing on airplanes and in a cabin with no network connection. It is a great option under these circumstances!
