The first step to embedding a playlist on your website is to create a playlist in the Manage -> Manage Videos -> Playlists -> Create Playlist section of the Sunday Streams Manager. Simply give the playlist a name, select the order of the playlist, then add videos to the playlist from the dropdown menu options. The drop down menu options contain all your public videos to select from (and also the live player as well).
Once you have created one or more playlists, you can then copy the playlist embed code from the Manage -> Manage Videos -> Playlists -> Embed Playlists section of the Sunday Streams Manager and paste the embed code directly on your website. NOTE: As you update videos in your various playlists, they will automatically update in your embedded playlists (i.e. you do not need to re-embed the playlist each time you update the videos in the playlist).
