In some situations it is useful to have a channel which has no just:out engine assigned to it. Such a channel is usually used to build a playlist, which then is transferred to an active "Online Channel" using the watch folder functionality or a playlist repository folder. Such an "Offline Channel" should have the same attributes like the "Online Channel" the playlists are made for. To build an "Offline Channel" based on an existing "Online Channel", select the "Online Channel" in the "Channel View" first and then click the "Offline Channel" button.
