According to the Netflix website, the discs will start arriving at members’ homes in one to two business days. To access streaming video content, users will need to put the discs into their Wii and enter the activation code (displayed on the television screen) into http://netflix.com/wii via their computer. After this initial set-up process, users will be able to see their Instant Streaming Queue from their Netflix account.
In order to be eligible for an instant streaming disc, you must have a $9 per month Netflix subscription (or higher).
If you don’t want to buy a new console, set-box, or DVD/Blu-ray disc player—you can order your free instant streaming Wii disc through the Netflix website, and start watching 480p instant streaming Netflix movies and TV shows…in one to two business days.
