To make a disc auto-play (no menus) just go the Movie Menu Adjustments workspace and click the Reset button. The menu template will be removed.
Thanks for the help, nice try but no cigar. I was able to get back to autoplay by checking "preferences/general/Show All Do Not Show Again Messages".
This reactivated the popup that asks if the disc is to be auto play. Your suggestion merely puts you back in project edit after clicking on "done".
Follow the link below ( I just now found it ) to see another dialog which fully explains the problem. Too bad the team responsible for this was not considerate enough to actually include the option that the online help claims is the way to go.
Glad you were able to figure it out, Richard. My solution would work on version 14. Sorry that it didn't on version 13.
