When you install the Vudu application on your device, you'll be taken to a log in screen that, first of all, prompts you to key in a valid email address. If you haven't created a Vudu account yet, you can create one by entering your email address carefully, entering each letter to ensure accuracy. It sends an email to that address. You can then go to your inbox and check your email for the Vudu activation key or code. Next, click the vudu.com/start link directly in the email and follow the instructions to set up your Vudu account.
