Hi, I've created a merged dvd with a menu to select movie. But when I play back on my standalone LG dvd-recorder, the disc remains at the first movie option and will not go to movie 2, and I can only get it by pressing the number 2 on the remote. But when the movie's menu starts, the remote works fine. I've tried the PUOPs settings but they are all unchecked. Is there something that I have overlooked?
