Blu Ray has become too much of a drama, so I am somewhat reluctantly looking to start purchasing my movies from iTunes. I'm a bit concerned about this issue of purchased movies being removed from libraries. I know that that recent Twitter faff resulted from the guy changing regions, but it was also confirmed that Apple can remove movies without warning based on licensing nonsense.
I know that iTunes lets you download movies offline (standard HD only) but they have DRM. I know there ways to remove that DRM but I don't like them. My question is: are the movies that iTunes downloads (on PC) discrete files that I can back up, and if I back these files up, can I be confident that I will be able to restore them to the iTunes media folder at a later date for playing via iTunes (in the event the movie is no longer downloadable/streamable from Apple's servers)?
Thanks.
