How can I watching TV shows and movies from Hulu or Netflix while being offline on my iPad or Nexus?

I'm a paid subscriber of both Hulu and Netflix and I'm a commuter that uses public transportation (i.e. subway), unfortunately lack of internet connectivity prevents me from using these services (Hulu/Netflix), so I'm looking for easy way to view Hulu and/or Netflix offline (w/out internet connectivity). disclaimer: I am _NOT_ trying to do anything illegal, I just want to be able to enjoy Hulu & Netflix by storing the content on either a Nexus 7 (preferably) or iPad mini. How can I do it?
