An "asset" is the movie file (or dynamic link to a Premiere sequence). The "timeline" is the Encore object you create that holds the asset. A playlist is an object that holds one or more timelines.
Set the end action of the timeline to itself. Put the timeline in a playlist. Set the end action of the playlist to "return to last menu." The button for repeating takes you to the timeline; the one play button 2 takes you to the playlist.
You can also use an override for this, but most users now avoid them. But it is a pretty simple application: set the end action of the timeline to "last menu." The one play button links to the timeline, with no override set. The repeating play button links to the timeline, but has an override set to the timeline.
Thanks! Both worked well. The assistance was much appreciated. Coming from Scenarist, the most difficult thing is just finding the new buttons and conventions. Thanks again!
