bool MenuLoop {get; set;}
True if the menu background loops continuously. False if the menu background video is played only once. This is the default value.
Gets or sets value that indicates whether the menu background loops continuously. Do not set this property to True if the menu background is a still image. If the background is a still image, there is no reason to loop since the image never changes.
Do not use the menu loop if the background contains a very short video. Some DVD drives take some time to restart playing the background and if it is a short video that can cause undesired effects. If you still want to use menu loop with a short video clip, obtain better results by concatenating the clip several times and using the longer clip as a menu. For example: To use a 1-sec clip as the menu in a continuous loop. Concatenate the clip 8 times, creating an 8-sec video clip (the original clip playing 8 times). Now use this 8-sec clip as the background and enable the menu loop.
