Thank you Steve. I now export an MPEG2 file & use 'Cyberlink - Power2Go 13' to author & burn to Blu Ray disc. I have been using PE since 2005 to make family movies. I am very disappointed with PE2019 for 2 reasons : two great tasks have been removed .... The 'Time Stretch' tool / Icon (ability to Time Stretch directly by dragging clip in Timeline) & ability to burn to Blu Ray.
