My first casting of a movie was painful. I'm using a rooted Thrive AT100. I rented a movie in the morning intending to watch it in the evening. That evening when I tried to watch, hit 'Play' in the Play Store and the Movies app started up but displayed a message saying that the rental had expired. Huh!! Went through this a couple of times and finally the movie started and the casting got underway. After 10 minutes the screen darkened (sleep mode) but the movie continued. After a while I pressed the power key to wake up the tablet to see how much of the movie was remaining, the time display was static, and still indicating the time from when the sleep mode started, and remained that way for 20 minutes or so. During that time I went back to the Play Store and clicked on 'Play', got the same rental expired message several times while the movie continued. Finally the movie time display started and the movie continued uneventfully until it finished. This is more trouble that I want to experience just to watch a movie. Can anyone explain what happened or what I might have done wrong?
