I would like a tablet for the primary purpose of buying movies and storing them onto microSD cards. First, I browsed the tabs in the store and noticed that Android's Media Hub market did not have everything I wanted. So, how do I find these movies for purchase? Can I copy already owned DVDs into my tablet somehow? I do not want to use websites (netflix, hulu, etc. that require a wifi signal and play commercials) I want to OWN the movies and television shows. Thank you so much!
