In the past few weeks Google added movie rentals to the Android Market, with prices starting $1.99 to rent a movie. This would be a great and convenient service which would have a lot of people excited, but unfortunately Google won’t let it work on rooted devices.
The Android Market help pages now state that if you are using a rooted device, movie rentals will not be available.
You’ll receive this “Error 49″ message if you attempt to play a movie on a rooted device. Rooted devices are currently unsupported due to requirements related to copyright protection.
Rooting an Android device is often the first step in getting the best performance from an Android device. Are you familiar with admin privileges on Windows OS? Rooting an Android device gives the user much the same level of control.
