This another really simple error that encore throws up every time you check your build unless you manually set it. This error is merely asking what the DVD should do once it has played the video track.
Use the dropdown, End Action to select how it should act, often it will be just Stop or return to the main menu.

No doubt you have come across this error many a time when you test your build in Adobe Encore especially if you have sent the project from Premiere Pro via Adobe dynamic link. This is merely the option to select what happens when the viewer presses the menu button on their remote control. If your project looks like the image displayed here then you don’t need to worry just ignore the error as it’s not really an error. I you have a menu on the disc you will need to select the drop down below and point it at your menu. You can pickwick this or select from the drop down.
