Android Central points out Google support document that details the Failed to fetch license for (movie title) error 49 message users will see when they try to play on a rooted device. Only Xooms with Android 3.1 have the access to the service right now, but support rolls out to all Android 2.2 or higher devices in a couple of weeks some had to choose between their superuser privileges and Googles nascent movie offerings. So far rooting and jailbreaking hasnt put a stop to other movie rental services for mobiles so even if Google blames the movie studios for the policy, it will be a odd restriction for the company behind the open platform to have.
