Movies or TV shows purchased from iTunes are DRM protected, this kind of protection intent to limit the use of digital content and devices after sale. To make these iTunes movies available on your tablet, you need strip off this protection using certain product like Pavtube ChewTune and convert to suitable video format like .mp4, then movies are playable on your Sony phone and tablet.
I just purchased a Google Nexus 7 today and attempted to transfer some itune movies to it for travel usage. But the converted file video quality is not as great as original ones, they are pixilated sometimes. Can anyone recommend a working software? Thank you.
