Hi Bob, Hi Paul,
I am not sure about the problem you encountered. So I can just guess.
First of all the duration of menu is not controlled by the length of background music.
It's controlled by three things.
* Preference Setting
a. Goto [Create Disc Preference]
b. The box of User-defined Motion Menu Duration (Max. 99s)
* The Menu style you are using.
If you are using Static menus (the menus not in Motion Style category), it's easy. The duration is decided by the value you put in the box.
If you are using "Motion Style", the audio duration (and the menu duration you put in the box) can not be longer than the background motion video duration, usually it's abount 10~20 seconds. That's the problem you two encountered, I guess. So you can change to Static Menus or if you just love the graphics of the motion menu.
a. Goto Create Disc Preference
b. Un-Check "Enable Video Thumbnail.
c. Set the duration you want at the box below it (Max. 99s)
* Chapter length
The last thing you should notice is for video thumbnail (the thumbnails whose content would play), menu duration can not be shorter than any chapter length. So if you have created an one-minute chapter, the menu duration can not be longer than 60 seconds.
Hope this helps.
