Thank you Stephen for your prompt response and I appreciate your feedback. My guess is that as DVD architect provides a preview facility of the project output prior to movie prep and burn and this currently indicates / displays the initial screen menu in 16.9 and then on selecting the movie play button from the menu screen, the movie displays in 4.3. I will burn a DVD+RW and come back with the results. I was just intrigued to see if anyone else had established the outcome. Off to the shops tomorrow for a rewritable disc. Cheers, Steve.
