I have just created a DVD project in DVDA 5.0b. There are many menus and submenus. When I preview the project in DVDA, everything works fine but when I go to create and burn the DVD, on playback of the DVD, the screen is black. No menus at all and the video does not play (although I can access the main video from the main DVD player menu). When creating the project in DVDA, sometimes the menu screens would also go black but would come back when I shut down the program and reopened it. This is very frustrating because I've been working on the menus alone for the past three days! I'm using a new Dell PC with Windows 7. Will try on my laptop which is running Vista, but would like to know why the menus are not burning properly to the DVD.
