I've yet to purchase a show or movie from the play store using my mobile or tablet. I assume that if I do, the shows/movies are viewable on the Co-Star also. Is this correct and, if so, which app will they show up in? Trying to decide if I want to start using the PlayStore for video. Currently I pretty much buy/rent video through Amazon Instant Video. Wish they had a native app for Android. I did look around a bit but did not see any definitive answer. Thanks.
