The update for Vizio TVs and Samsung devices is in the works, but everyone else should have access now.
If you have a device hooked up to your home theater that sports Vudu integration, you'll be greeted with a brand new interface when you turn it on. There's no need to download anything or set anything up - everything happens automatically.
The new Vudu interface provides you with faster access to the movies you want to watch, a recommendation list based on your viewing history, as well as browsing and navigation tweaks designed to make things quicker and easier.
Those using Vudu on a Vizio TV or Samsung device are out of luck - the update for Vizio and Samsung is still in the works, though Vudu says that they expect to roll it out soon.
