I updated to the latest NVE and I stil have this problem.
Sometimes at random I make a DVD with menus and the menus are unable to be chosen. Even if I hit the corresponding numbers of the menu it doesn't play.
This is happening on three DVD platyers a Sony, Samsung and Philips.
If you want to see an example, see the video below. The first part is a normal DVD made on the same PC as the second part.
