We learned last week that Walmart’s video streaming & download service Vudu was coming to Apple TV, and it’s now available – with a handy feature for those with large Blu-ray and DVD libraries.

Vudu supports Ultraviolet, a feature that provides digital access to some movies you bought in physical disc format …

Some discs include an Ultraviolet redemption code which provides free streaming and download access to the same movie. If your disc doesn’t include the Ultraviolet or UV tag, CNET notes that you may still be able to purchase a digital version for just $2 for a standard-def version or $5 for high-def.

Once you’ve done this, the movies are added to your Vudu library and you can watch them in the Vudu app, freeing you from the need to mess around with physical discs.

While you can watch any of your existing Vudu library content, as well as the free movies offered by the service, you can’t rent or buy anything in the Apple TV app. This is because Apple would want its cut of in-app purchases.
