I authored a Blu-ray disk that has a single long video file of a classical concert. The main disk menu has three buttons for entry points into the file, one for each section of the concert. That all works fine, and I've done this before. Here's the problem. When I press F9 in DVD Architect to preview the project, the menu comes up and it waits for me to click one of the buttons. But when I burn the disk and put it into my new Sony Blu-ray player, the concert begins playing immediately. I have to press Top Menu on the player's remote to get it to stop and show the main menu. What should I do to have the menu show initially, rather than just start playing the disk? For reference, my computer is a Dell running Windows 7 Professional, and everything else on this computer works perfectly including Vegas Professional. Thanks!
