If you are already in a collection, from the Zappiti Video menu select "Logout...".
The Offline mode with server allows the use of your collection with a local server without an internet connection.
The collection will be read-only, which does not permit modifications.
Open the "Zappiti Servers" selection page
Choose your local server.
Select "Offline mode with server".
Once connected to your collection, only the read-only options are available.
